<h2>What is decimal time?</h2>
<p>Decimal time is a method to write and display a date and time
in decimal notation, either worldwide or local based on legacy
timezones.</p>
<ul>
<li>Years are counted from the Unix Epoch (Jan. 1st, 1970
in legacy time).</li>
<li>Time is counted by number of days (counting from zero)
elapsed during the year, plus the decimal fragment of day
already elapsed up to five decimal digits (deciday,
centiday, milliday, decimilliday, centimilliday
respectively).</li>
<li>As of yet, decimal time has been only implemented for
terrestrial dates, hence the T suffix after the year.</li>
<li>Worldwide time is indicated by an M suffix, while local
timezones use a L prefix followed by the amount of offset
that must be added or substracted in decimal time to reach
legacy UTC.</li>
</ul>
