Offset. Use this menu item to set the DST offset that will be applied when either
the Once event or the DST START event occurs at the user-scheduled time.
Press the ENTER button, and then use the left (◄) or right (►) arrow button to
select a digit in the DST offset value to change. An underline character appears
under the selected offset digit. The date and time digits take the following form:
HH:MM. When the DST Schedule function is set to Recurring, this offset can
only be a positive number.
After you select an offset digit, use the up (▲) or down (▼) arrow button to
change the value of the digit. Repeat for each digit as required for your offset.
Press the ENTER to confirm the offset change.
ONCE. Press the ENTER button, and then use the left (◄) or right (►) arrow
button to select a digit in the DST setup value to change. An underline character
appears under the selected digit. The date and time digits take the following
form: YYYY-MM-DD HH:MM:SS.
After you select a digit, use the up (▲) or down (▼) arrow button to change
the value of the digit. Repeat for each digit as required for your date and time.
Press the ENTER to confirm the change.
NOTE.
When the DST Once event occurs, the scheduled offset will be either added
to or subtracted from the time zone offset, and the DST schedule will be cleared.
This allows for a new schedule to be set up for any time in the future.
VITC may have DST shift already applied. To avoid duplicating DST shifts,
disable the DST SCHEDULER if the time of day reference has DST applied.
RECUR <Start / End>. There are two Recurring selections: Start and End. The
DST Start time is the time when the DST offset you enter will be added to the time
zone offset. The DST End time is the time when the DST offset will be removed.
The DST Start and DST End times are edited in the same manner. Press the
Enter button, and then use the left (◄) or right (►) arrow button to select a
digit in the DST START or DST END value to change. An underline character
appears under the selected digit. The date and time digits take the following
form: Week-Day-Month HH:MM:SS. After you select a digit, use the up (▲) or
down (▼) arrow button to change the value of the digit. Repeat for each digit as
required for your date and time.
For example, if you enter First-Sun-Mar 02:00:00 for the DST Start time, the DST
offset you entered would be added to the time zone offset on the first Sunday in
March at 2 AM. The Week field can be set to the First, Second, Third, Fourth, or
Last. Press the ENTER to confirm the change.
NOTE.
If you enable the Recurring function at a time between the Start and End
settings, the DST offset is immediately applied when you press the ENTER button.
