Dear All,

The system clock of our Zope 2.7 machine accidentally got set to 2009.
We noticed this mistake 6 hours later and we decided to set back the
clock to 2008.

How does this affect the integrity of Data.fs ?

From our observation :

1. Session write errors suddenly began to appear

2. Data.fs.index won't grow anymore and its timestamp remained at the
time we set back the clock

3. Packing the database (which was 8 GB at the time) took too long
without any signs of any Data.fs.pack file in the var folder. We decided
to restart Zope after a few minutes.

4. There seem to be some catalog indexing problems as our catalog
searches on a certain field doesn't work as reliably as it did before.
We tried reindexing the field and even the catalog, but it timed out on
us (lots of objects in the database).

Has anyone here had any similar experiences ? How do I go about fixing
this ?

Turning the clock back is known to result in data inconsistencies.
It is is best-practice having NTP installed on all Zope machines.
