Hi Gunhan Kiratkar, 

I have checked the cases which are updated recently there is no update on user timezone but why contact local time is updating..

Hi @lucky6 

There is one more field on case table as contact timezone.

If that is field updates then contact time will also update.

I wanted to point out the above is not correct. Calculated fields update any time -anything- on the record updates, not just some supposedly dependant field. It also updates as a separate action than the originating update, meaning business rules/engines/etc. get triggered twice as well. Just for anyone else coming across this.
