Wrong Time / CoreTime Errors

After applying the latest untethered jailbreak, my system clock time is wrong.  The time seems to be 90 mins too early.

Setting the general Time Zone settings to auto or manual doesn’t fix it, nor does changing the time zone, or rebooting.

I tried this terminal solution via SSH but it doesn’t work either.

My system log shows a number of errors related to CoreTime.  This is not my system log but some else’s that I found on google; but the main errors are the same.  They include lines like “Can’t Set time zone to nil!”

Has anyone else seen anything like this?   Could it have to do with the jailbreak?  Any solution?
