DST Reference: When configuring a Local Clock that is synchronized to an input

time (Local Timescale, or UTC Timescale), in order to provide proper internal con-
version from one Timescale to another.
Select Local or UTC, depending on the Timescale of the Input reference this
Local Clock is being used with.
Additional Local Clocks may need to be created if multiple input Timescales are
being submitted.
