Daylight Savings
Time Controls whether displayed time is daylight savings time or not. If set to “Yes”
and the Optional Rule is empty, then the displayed time will be 1 hour ahead of
normal time.
• The “Automatic Daylight Saving Time Rule” has the following syntax:
o start-time;end-time;saving. Both start-time and end-time have
the same syntax: month,day,weekday,hour,minute
o month: 1,2,3,..,12 (for Jan, Feb, .., Dec)
o day: [+|-]1,2,3,..,31
o weekday: 1, 2, 3, .., 7 (for Mon, Tue, .., Sun), or 0 indicating
daylight savings rule is based on the day of the month.
o hour: hour (0-23),
o minute: minute (0-59)
• If “weekday” is 0, it means the date to start or end daylight savings is
the given date. The “day” value must not be negative.
• If “weekday” is not zero and “day” is positive, then daylight saving starts
on the first “day” of the week (1st Sunday, 3rd Tuesday etc).
• If “weekday” is not zero and “day” is negative, then daylight savings
starts on the last “day” of the week (last Sunday, 3rd last Tuesday etc).
• Daylight savings is in minutes. If preceded by a (-), then subtract the
number of minutes.
