/* This plugin will convert standard time to metric time.
 *
 * As with my Ship Time plugin, this is a rewrite of a program I wrote in college many years
 * ago in Turbo Pascal 3.0.
 *
 * Back in high school (mumble-mumble years ago), I devised a system of metric time where
 * the day was divided into 10 hours, each hour divided into 100 minutes, and each minute
 * divided into 100 seconds.
 *
 *  Majoring in math and computer science in college, I wrote a Pascal program to implement my
 *  metric time system.
 *
 * This was before the Internet was a thing, so I didn't know that some companies and
 *  countries already toyed with metric time standards and had come up with
 *  systems very similar to mine.
 *
 * To get the current time, issue /METRICTIME .  To convert standard time to metric time,
 * issue /METRICTIME hh:mm:ss .
