%SubTime function


Old name
%SubTimeT


Function
The function subtracts a relative time TimeR from an absolute time TimeA. The result is absolute time.
Declaration
TIME  %SubTime(
   TIME in TimeA, 
   REAL in TimeR,
   TEXT in timeZone := %GetCurrentTimeZone()
)
Parameters
TimeAAbsolute time.
TimeBRelative time.
timeZone

Name of the time zone used for conversion to local time (e.g. "Europe/London") or definition of fixed offset from UTC using format "(+|-)hh[:mi[:ss]]", where hh defines a number of hours, mi defines a number of minutes, and ss defines a number of seconds. Sign as well as a number of hours are mandatory parts of offset definition, number of minutes and seconds are optional and default to 0 (e.g. "+02:30" defines offset of 2 hours and 30 minutes from UTC). The empty text has the same meaning as function %GetCurrentTimeZone.
Note: For historical reasons, an integer parameter is also accepted. Its interpretation is as follows: 0 - zone "Europe/London", 3600 - zone "Europe/Bratislava", 7200 - zone "Europe/Kiev", 21600 - zone "Asia/Almaty". Usage of integer parameter is deprecated and generates warning into log file!

Note
Function works like the function %SubTimesLocal.
