7. DST Start Date and DST End Date: This option is provided for locations that
do not follow any of the pre-configured DST rules. Click anywhere in either
field to open a calendar, allowing you to enter any custom day & time rule.
8. Offset: In seconds. Use this field to manually define your local clock’s DST
offset e.g., 3600 seconds for a one hour offset.
9. DST Reference: When configuring a Local Clock that is synchronized to an
input reference (e.g., IRIG input), VersaSync needs to know the timescale of
the input time (Local Timescale, or UTC Timescale), in order to provide
proper internal conversion 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.
10. Click Submit. Your local clock will appear in the Local Clocks panel.
