getPOSIXTime :: PandocMonad m => m POSIXTime

Get the POSIX time. If SOURCE_DATE_EPOCH is set to a unix time, it is used instead of the current time.

time-compat Data.Time.Clock.POSIX.Compat, rebase Rebase.Prelude

Get the current POSIX time from the system clock.

Return the current system POSIX time via gettimeofday, or getSystemTimeAsFileTime on Windows. See also getCurrentTime, getZonedTime.
