i faced such issues before. i connect to NTP server and the issue never occured again. if you do not have NTP server try to make your voice gateway the NTP server and i should solve your problem

might be a legacy phone load issue.  What version of CUCM and what phones do you have.

In most cases, the time zone options that are marked with ‡ are compatible with all phone loads.

The following phone models that run firmware 9.0(2) (or higher) are fully compatible with all time zones that are listed in the drop-down list box:
7906, 7941, 7942, 7945, 7961, 7962, 7965, 7970, 7971, 7975, 89xx and 99xx

What are the phone models been affected? as well what's your CUCM and firmware version on the phone? How much time is the phone off?

In  7.1.3 and higher you may need to choose a timezone with an asterisk for legacy phones.

Looking forward to hearing from you.
