The function returns the serial number of the week of given
absolute time.
Declaration
INT %WeekOfYear(
TIME in time,
INT in timeZone := %GetTimeZone()
)
Parameters
time
Function argument.
timeZone
Forced time zone to convert to a local time. It is
set as a time zone offset from UTC during winter in seconds.
Note
Possible values range from 1 to 53. For yearly recurrence
pattern rules, the first week of the calendar year is the first week that
contains at least four days in that calendar year.
If the last week of a
year and the first week of the next year are the same week, the function
returns the same value for both the weeks (the same system as in the
calendar).
