PCJ-No timezone information in the exported data
Problem
The exported data will certainly contain date/time fields but no reference to the timezone where those values are valid. As a result, if the source and target instances use different timezones, the time values will be shifted by the time difference between those zones. See these bug reports   - JSWSERVER-5433Restoring Sprint data in a different server timezone broken RESOLVED  and   - JRASERVER-26039Verify the system timezone when an XML backup is restored RESOLVED
The workaround: make sure that source and target instances are using the same timezone.
