Convert Date and Time to Julian Date or POSIX Time, Convert Zoned and Unzoned Datetime Values to Julian Dates, Convert Zoned and Unzoned Datetime Values to POSIX Times. Scaliger got the idea of using a tricyclic period from "the Greeks of Constantinople" as Herschel stated in his quotation below in Julian day numbers.

An error of about 1000light-seconds is over 1% of a light-day, which can be a significant error when measuring temporal phenomena for short period astronomical objects over long time intervals. Thus, time zones representation is applicable only for conversions to naive DateTime. Time Difference. Time intervals calculated from differences of Julian Dates specified in non-uniform time scales, such as UTC, may need to be corrected for changes in time scales (e.g. Amazfit one Copy.
