Choose what time zone offset should be used when date and time values are specified. The format is {+|-}HH[:MM[:SS]] where:

• +|- is the offset direction. Specify + to indicate that the offset is East of the zero median (UT). Specify - to indicate that the offset is West of the zero median (UT). The offset direction is required.
• HH is hours
• MM is minutes
• SS is seconds

An optional colon (:) separates hours from optional minutes and optional seconds.
