Hammer timestamps are blindly treated in UTC and does not honour user or system timezone.

Issue

• After creating a sync-plan with "hammer sync-plan create" command, it is set in the UTC timezone, regardless what timezone the specified user has.

• When a job invocation via hammer to be started at a given time, the time is again interpreted in UTC regardless of any locale.

• WebUI does not respect the user's or brower's timezone well.
