May I assume that if you issue your command at 00:00:00.5, the timer pops in another 0.5 seconds, which may or may not be what you intend.
Ugly. If STIMER LT is issued close enough to the requested time it's unpredictable, depending on code path and dispatchability, whether it waits for 0.01 second or 863399.99 seconds. Ugly; ugly! If the request is for an interval, just add it to the TOD value and load the Clock Comparator. If the request is for LT or GMT, compare to current time, If the requested time is less than the current time, add a day. If GMT, adjust for leap seconds when they occur. If LT, adjust for leap seconds and Daylight Saving Time boundaries when they occur. My head hurts. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
