Clock

This is a C time library wrapper for getting system time to support Dates.Mod. The procedures are read only as setting time is non-standard on many Unix-like systems[^1]. The two procedures follow the A2 style procedure signatures adjusted for Oberon-07.

Source code for Clock.Mod

MODULE Clock;

PROCEDURE GetRtcTime*(VAR second, minute, hour, day, month, year : INTEGER);
BEGIN
END GetRtcTime;

PROCEDURE Get*(VAR time, date : INTEGER);
BEGIN
END Get;

END Clock.
