TIME (DATE AND TIME handling)

RAVEN stores all times and dates in UTC in DB and internally all is UTC
User has a timezone offset setting which is used to format dates for display at the client
Dates coming from the client are all assumed to be in UTC format (i.e. converted at the client from input)
TimeZoneOffset is also used for relative date filters in list filter retrieval.
    - i.e. "NextMonth" is assumed to be client relative, so the server will use their offset to calculate what next month meens to them in the query builder
