Spigot plugin for time management and display

TIME MANAGEMENT FUNCTIONALITIES
Define a start time and a speed modifier per world. Set a suitable refresh rate for the performance of your server.
Speed could be increased/decreased up to 20 times or match UTC time with offset to local time.
Day and night can be set to different speed values, which can be great for RPG or some mini-games.
Worlds list is actualized and timers are synchronized on each server startup and reload.
Time and speed can be modified or synchronized with in-game commands or reloading after manually changes.
A specific time offset can be defined for each player.
TimeManager can schedule commands that run at a time specified in the cmds.yml file. Scheduled commands can use the placeholders described below, with the exception of {tm_player}.
This plugin override the vanilla '/time' command. The command to change a single world time is '/tm set time [ticks|daypart|HH:mm:ss] [world]'.

SLEEP MANAGEMENT FUNCTIONALITIES
TimeManager allows you to manage sleep: number of players required, animation during night skip, synchronization between worlds when waking up, etc.
Sleep can be authorized, forbidden or linked with some other worlds.
individual permissions can also be used.

PLAYER COMMAND /now <display> <world>
A single command is used to display a custom message with the time, the date, the number of elapsed days or weeks, or many other placeholders.
/now messages support multi-language and could automatically be accorded to any player's locale available in the lang.yml file.
Using the permissions, you can permit players to choose the display and/or the world argument or neither of the two.
Display argument can be : 'msg', 'title' or 'actionbar'.
Nether and the End worlds could have a specific message.
Hexadecimal colors can be used in the YAML files.

PLACEHOLDERS
The available placeholders are as follows :

• {tm_player} : Displays the name of the player.
• {tm_world} : Displays the name of the world.
• {tm_tick} : Displays the current tick.
• {tm_time12} : Displays the current time in hh:mm:ss format. (1 → 12)
• {tm_time24} : Displays the current time in HH:mm:ss format. (0 → 23)
• {tm_hours12} : Displays the current hour value in 2 digits. (1 → 12)
• {tm_hours24} : Displays the current hour value in 2 digits. (0 → 23)
• {tm_minutes} : Displays the current minutes value in 2 digits.
• {tm_seconds} : Displays the current seconds value in 2 digits.
• {tm_ampm} : Displays the current AM or PM part of the day.
• {tm_daypart} : Displays the name of the current part of the day, among the four existing ones, in each of the languages.
• {tm_currentday} : Displays the number of the current day. (1 → ∞)
• {tm_elapseddays} : Displays the number of elapsed day(s). (0 → ∞)
• {tm_dayname} : Displays the name of current day, based on entries in the lang.yml file.
• {tm_yearday} : Displays the number of the day in the year. (1 → 365)
• {tm_yearweek} : Displays the number of the week in the year. (1 → 52)
• {tm_week} : Displays the number of elapsed weeks. (1 → ∞)
• {tm_monthname} : Displays the name of current month, based on entries in the lang.yml file.
• {tm_dd} : Displays the day part of the date in 2 digits.
• {tm_mm} : Displays the month part of the date in 2 digits.
• {tm_yy} : Displays the year part of the date in 2 digits.
• {tm_yyyy} : Displays the year part of the date in 4 digits.

Please note that these placeholders are case sensitive.
They can be used in lang and cmds YAML files, but also in signs, books, chat messages and commands.

Dependencies
TimeManager can display its placeholders through PlaceholderAPI and MVdWPlaceholderAPI. You just need to place the API in your plugin folder and set the related node to 'true' in the TimeManager config.yml file.

ADMIN COMMAND /tm
/tm checkConfig Admins and console can display a summary of the config.yml and lang.yml files.
/tm checkSql Check the availability of the mySql server according to the values provided in the config.yml file. This only checks the ip address and the correct port opening.
/tm checkTime [all|server|world] Admins and console can display a debug/managing message, who displays the startup server's time, the current server's time and the current time, start time and speed for a specific world (or for all of them).
/tm checkUpdate [bukkit|spigot|github] Search if a newer version of the plugin exists on the chosen server. (MC 1.8.8+ only)
/tm help [cmd] [<subCmd>] Help provides you the correct usage and a short description of targeted command and subcommand.
/tm now [msg|title|actionbar] [player|all|world] Send the '/now' (chat, title or action bar) message to a specific player, all players in a specific world, or all online players.
/tm reload [all|config|lang|cmds] This command allows you to reload datas from yaml files after manual modifications. All timers will be immediately resynchronized.
/tm resync [all|world] This command will re-synchronize a single or all worlds timers, based on the startup server's time, the elapsed time and the current speed modifier.
/tm set date [today|yyyy-mm-dd] [all|world] Sets current date for the specified world (or all of them). Could be today or any yyyy-mm-dd date. The length of the months corresponds to reality, with the exception of February which always lasts 28 days. A year therefore always lasts 365 days.
/tm set debugMode [true|false] Set true to enable colored verbose messages in the console. Useful to understand some mechanisms of this plugin.
/tm set defLang [lg_LG] Choose the translation to use if player's locale doesn't exist in the lang.yml or when 'useMultiLang' is false.
/tm set debugMode [true|false] Set true to enable colored verbose messages in the console. Useful to understand some mechanisms of this plugin.
/tm set duration [00d-00h-00m-00s] [all|world] Sets the speed of the world based on the desired duration rather than with a speed multiplier.
/tm set durationDay [00d-00h-00m-00s] [all|world] & /tm set durationNight [00d-00h-00m-00s] [all|world] The length of day and night can be defined separately.
/tm set elapsedDays [0 → ∞] [all|world] Sets current number of elapsed days for the specified world (or all of them). Could be an integer between 0 and infinity (or almost). Setting this to 0 will bring the world back to day one.
/tm set firstStartTime [default|previous|start] [all|world] Forces the time at which a world starts when starting the server. The value 'default' allows the usual resynchronization at startup. The value 'start' forces the world to start at the time specified in the world's 'start' node. The value 'previous' returns the time in the world before the server was shut down.
/tm set initialTick [ticks|HH:mm:ss] Modify the server's initial tick.
/tm set multiLang [true|false] Set true or false to use an automatic translation for the /now command.
/tm set playerOffset [-23999 → 23999] [all|player] Define a specific offset relative to the world time on player's client (the world speed will be still active). Set to '0' to cancel.
/tm set playerTime [ticks|daypart|HH:mm:ss|reset] [all|player] Define a specific time on player's client (the world speed will be still active). Use the 'reset' argument to cancel.
/tm set refreshRate [ticks] Set the delay (in ticks) before actualizing the speed stretch/expand effect. Must be an integer between 2 and 20. Default value is 10 ticks, please note that a too small value can cause server lags.
/tm set sleep [true|false|linked] [all|world] Define if players can sleep until the next day in the specified world (or in all of them). By default, all worlds will start with parameter true, unless their timer is in real time who will be necessary false. If you want to both allow sleep and keep the same time in multiple worlds, you can use the 'linked' function which allows a group of worlds to spend the night together.
/tm set speed [0.0 → 10.0] [all|world] The decimal number argument will multiply the world(s) speed. Use 0.0 to freeze time, numbers from 0.1 to 0.9 to slow time, 1.0 to get normal speed and numbers from 1.1 to 10.0 to speed up time. Set this value to 24.0 or realtime to make the world time match the real speed time.
/tm set speedDay [0.0 → 10.0] [all|world] & /tm set speedNight [0.0 → 10.0] [all|world] From 0.0 to 10.0, the values of daySpeed and nightSpeed can be different from each other.
/tm set start [ticks|daypart|HH:mm:ss|timeShift] [all|world] Define the time at server startup for the specified world (or all of them). By default, all worlds will start at tick #0. The timer(s) will be immediately resynchronized. If a world is using the real time speed, the start value will determine the UTC time shift and values like +1 or -1 will be accepted.
/tm set sync [true|false] [all|world] Define if the speed distortion method will increase/decrease the world's actual tick, or fit the theoretical tick value based on the server one. By default, all worlds will start with parameter false. Real time based worlds and frozen worlds do not use this option, on the other hand this will affect even the worlds with a normal speed.
/tm set time [ticks|daypart|HH:mm:ss] [all|world] Set current time for the specified world (or all of them). Consider using this instead of the vanilla /time command. The tab completion also provides handy presets like "day", "noon", "night", "midnight", etc.
/tm set update [none|bukkit|spigot|github] Define the source server for the update search. (MC 1.8.8+ only)
/tm set useCmds [true|false] Set true to enable a custom commands scheduler. See the cmds.yml file for details.

TUTORIALS



COMPATIBILITY

• v1.10.0: MC 1.9.4 to 1.21.3

API
Although the plugin is not intended to be an API, it is possible to use the different placeholders by importing the PlaceholdersHandler class in your Java code :

import net.vdcraft.arvdc.timemanager.mainclass.PlaceholdersHandler

Then use one of the following methods to transform one or more placeholders in any string :

String replaceAllPlaceholders(String msg, String world, String lang, Player p)
String replaceAllPlaceholders(String msg, String world, String lang)
String replaceAllPlaceholders(String msg, World w, String lang, Player p)
String replaceAllPlaceholders(String msg, World w, String lang)

It is possible to retrieve the client language by importing the following class :

import net.vdcraft.arvdc.timemanager.mainclass.PlayerLangHandler

Then use one of the following of the following methods :

String setLangToUse(CommandSender sender)
String setLangToUse(Player p)
