The same happened to me some time ago and it was rather difficult to 
debug. In our case, the timezones were fine but one clock was running 
several minutes behind. This had the effect that some phones got 
unregistered for half a minute or so.

It turned out that our ubuntu installations did only do an NTP sync at 
boot time. So, in addition to "timezones do matter" one should always 
setup an NTP daemon on all proxies in a cluster.
