Due to incompatibility with most plugins that manage sleep, TimeManager has been modified to introduce its own sleep management with an "instant" option and an "animation" option to spend the night.
A system of number of players required to sleep has been implemented.
New permissions have also been created.
Placeholders
Added the placeholder {tm_dayname}
Added translations in the lang.yml file
Changed some calculation methods for dates, using java.time.LocalDate
Leap years are now taken into account in the calculations
Bug fixes
Commands: Fixed misinterpretation of negative UTC values in the 'set start' command
Config.yml : 'start' now accepts a UTC+/-n formatted value
Backwards compatibility
The entire plugin's backwards compatibility has been reworked to work up to Minecraft version 1.9.4.
