Query UTC-stamped transactions with an off-set that respects local timezone

Sometimes data from international companies are stamped with UTC-timestamps. However in the TARGIT anaylsis they wish to respect the local timezone of the user logged into TARGIT and show data in local timezone. 

This will require an off-set on hours (like the offset we currently support on dynamic date origin) that is set based on the users location.

The minimum viable product here could be linked to OpenID and TARGIT InMemory only. 

This is raised by partner Lyngsø.
