UnixTimeToTimestamp

Basic

Module: FoundationLite

Converts Unix time to timestamp.

Name Type Description
Input value inUnixTime Long Unix time (seconds part)
Input value inNanoseconds Integer Nanoseconds part, in range <0;999999999>
Output value outTimestamp Timestamp UTC timestamp

Remarks

Assumptions about date and time calculations:

  • Timestamp should always be in UTC (Coordinated Universal Time).
  • Timestamp can be converted to DateTime using either UTC or local timezone. Other timezones are not supported. However, the timezone offset is saved in DateTime so one can always convert back to UTC.
  • Conversion to local time should take into account daylight saving time (summer/winter time), if configured in the operating system. However, usually only currently applicable DST rules are used, so calculations may be incorrect if they refer to a period when the rules were different.
  • Timestamp resolution is 100 nanoseconds.
  • Timestamp is 64-bit, so should support dates about 29000 years in the past or future. However, the whole range may not be supported when converting to local timezone.
  • Dates are calculated in proleptic Gregorian calendar.
  • Leap seconds are ignored, like in Unix time.
