Custom Daylight Saving Rule – Starting Value for Mode 24-n=10
Default=327 – (Second Sunday in March)
Values for rule driven custom daylight saving time for Mode 24-n=10. The
format is MMRD, where MM = month (1-12), R = instance of the select day of
the week (1-5 5=last instance), D = day of the week (1-7), where 1=Monday
and 7=Sunday. For example, the number 357 represents the last Sunday in
March, or 1117 represents the First Sunday in November. If the value >2000
then the right two digits represent the day of the month. The left two digits,
minus 20, equal the month. For example, March 15th = 2315, April 1st =
2401. The day of the year derived from this rule is stored in Mode 52-1.
If
the DST date is a fixed day (i.e. 15
th
of the month), then set this mode to
0 and enter the Julian day into Mode 52-1 instead.
