Log Message:
Collector 1327:  FileStorage init confused by time travel

If the system clock moved back in time more than 30 days between
a FileStorage close and (re)open, new txn ids could be smaller
than txn ids already in the database.  Plugged that hole.

Includes a stripped-down rewrite of the new test in ZODB 3.3.  Main
difference is that this version doesn't automatically check that new
log messages are actually produced; that's easier to do in 3.3,
building on an extension to the logging package Jim wrote for Zope 3.

+Collector #1327 FileStorage init confused by time travel.
+If the system clock "went backwards" a long time between the times a
+FileStorage was closed and reopened, new transaction ids could be
+smaller than transaction ids already in the storage, violating a
+key invariant.  Now transaction ids are guaranteed to be increasing
+even when this happens.  If time appears to have run backwards at all
+when a FileStorage is opened, a new message saying so is logged at
+warning level; if time appears to have run backwards at least 30
+minutes, the message is logged at panic level (and you should
+investigate to find and repair the true cause).
