I've got zpush setup and running on a CentOS box working wonderfully. The only issue thus far is that all messages are showing up from the date in the thread title. Appointments come across normally.
Can anyone point me in the right direction? From, my searches, I've managed to confirm that this date is significant to the UNIX time standard in some way. from my searches "that date is, apparently, exactly 2^32 -1 seconds after the Unix epoch."
