trigger at TDM/2 only

Hi,
I have a process that I can trigger only at a certain time. Assume I have a TDM period of 10min, that means, I can only fire my trigger at the 5th minute of every 10min cycle i.e. at XX:05, XX:15, XX:25... For hat I came up with following algorithm which oly leaves the waiting while loop if minute % TDM/2 is 0 but not if minute % TDM is 0:
min = datetime.datetime.now().timetuple().tm_hour*60 + datetime.datetime.now().timetuple().tm_min
while not (min%tdm_timeslot != 0 ^ min%(int(tdm_timeslot/2)) != 0):
time.sleep(10)
logger.debug("WAIT "+str(datetime.datetime.now().timetuple().tm_hour*60 + datetime.datetime.now().timetuple().tm_min))
logger.debug(str(min%(int(tdm_timeslot/2)))+" - "+str(min%tdm_timeslot))
min = datetime.datetime.now().timetuple().tm_hour*60 + datetime.datetime.now().timetuple().tm_min
logger.debug("RUN UPDATE CHECK...")
But weird enough, the output I get is something like this:
I would expect my while to exit the loop as soon as the minute turns 1435... why is it staying in? What am I doing wrong here?
WAIT 1434
3 - 3
WAIT 1434
4 - 4
WAIT 1434
4 - 4
WAIT 1434
4 - 4
WAIT 1434
4 - 4
WAIT 1434
4 - 4
WAIT 1435
4 - 4
WAIT 1435
0 - 5
WAIT 1435
0 - 5
WAIT 1435
0 - 5
WAIT 1435
0 - 5
WAIT 1435
0 - 5
WAIT 1436
0 - 5
RUN UPDATE CHECK...
Thank you for any assistance!
Ron
