This is a showstopper for us. We've had to rollback to 7.2.11 on our production machines and we'll be unable to upgrade to any new version until this bug is fixed. It looks like it's related to the latest timelib upgrade. It looks like you should revert that change in the next version until all the edge cases are solved. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
