Thanks to all who responded (Dennis, Dieter, Paul). I'm going to work on getting my system clocks in sync, as this sounds like a reasonable explanation. --- Paul Winkler <pw_lists@slinkp.com> wrote:

When I synchronize using ZSyncer, very frequently the indicator text beside the folder still shows as "out of date" even though it is not (the date and content are correct). Is this typical? And what can I do? Because this happens, I am syncing a lot of folders that probably don't need it.
This is a known limitation. It happens when the source system's clock is a bit (or a lot) ahead of the destination. So you modify something and immediately sync it and the destination modification time is returned as older than you think.
To prevent it in the future, ensure that the source and destination servers have their clocks set as close as possible. However, this won't help with existing objects.
Current CVS of zsyncer tries uses DublinCore timestamps instead of bobobase_modification_time, when possible. This gives better results for CMF content.
Unfortunately, it's hard to do better for most other zope types, because they only provide bobobase_modification_time, which is under control of the underlying ZODB and cannot be overridden by zope.
There are plans to investigate checksumming and other strategies for more reliably determining sync status, but currently I don't have much time for this.
