time systems
got some different systems of measuring time over a day (clocks) or over a year (calendars)
they utilise different bases and i would not use any of the clocks cause i am in no way wanting to redefine the SI base unit of time (the second)
all numbers in descriptions are base 10 unless otherwise specified

ISO 8601 (extended format)
loading
12 months in a year, a variable number of days (ranging from 28 to 31) in a month, 365 days in a year (366 days if the year is divisible by 4, but 365 days if the multiple of 4 in question is also a multiple of 100 that's not a multiple of 400), 24 hours in a day, 60 minutes in an hour, 60 seconds in a minute
the ISO 8601 standard extended format represents the time and date in a yyyy-mm-ddThh:mm:ss.fZ format, where yyyy is a four-digit year, mm is a zero-padded two-digit month, dd is a zero-padded two-digit date, hh is a zero-padded 24-hour two-digit hour, mm is a zero-padded two-digit minutes value, ss is a zero-padded two-digit seconds value, and f is the fractional part of the second
the T separates the date and time, and the Z indicates that a timezone of UTC+0 is being used
if a time zone other than UTC+0 is being used, the Z is replaced with a plus or minus followed by the time zone offset, e.g. +11:00 for australian eastern daylight time or -05:00 for standard time in new york
hexadecimal time
loading
each day is split up into 65536 (10000 in hexadecimal) parts; the time is represented with the hexadecimal number of those parts that have elapsed during the day
one part in hexadecimal time is equal to exactly 1.318359375 regular seconds
countdown until time
: :enter in a time (24-hour hour-minute-second) in the dropdowns above and click the "enter time" button

decimal time
loading
time is represented as a percentage of the day, e.g. 0.000 is midnight, 50.000 is noon, and 12.345 is about 2:57 AM
each "second" of decimal time (1/10000 of a day) is equal to exactly 0.864 regular seconds
decimal time (french revolution style)
loading
each day is split up into 10 hours (2 regular hours and 24 regular minutes), each hour is split up into 100 minutes (86.4 regular seconds), and each minute is split up into 100 seconds (0.864 regular seconds)
swatch internet time
loading
this was a decimal time system invented in 1998 by a watch company (swatch) to promote a line of watches
each day is split up into 1000 ".beats" and time is represented by an @ followed by the number of beats elapsed of the day
this is pretty unique because there are no time zones; it is always fixed to UTC+1 (biel mean time)
so like @0 swatch internet time is midnight UTC+1 and @500 swatch internet time is noon UTC+1
