PL/SQL API time.calc_win

Summary

procedure calc_win(wpart in varchar2, wname in varchar2, ts in out timestamp with time zone, mts in timestamp with time zone) (Unsupported)
function calc_win(wpart in varchar2, wname in varchar2, ts in out timestamp with time zone, mts in timestamp with time zone) return timestamp with time zone (Unsupported)

Calculate the first time a Time Window opens after a given start datetime.

Note: The function always stops at 24 months in the future from ts. mts can be used to further restrict this period.
