w - Week (first(1), second(2), third(3), fourth(4), last(>4))
d - Day (Sunday(1), ..., Saturday(7))
m - Month (January(1), ..., December(12))
hh:mm - time of day DST changes (0-23:0-59)
HH:MM - offset DST changes by. (0-23:0-59)

Returns disabled if disabled.What is chasTimezoneDst?
This object encodes the full DST transition rule for the chassis in a fixed 20-byte structure specifying the week/day/month/time the clock should spring forward, the week/day/month/time it should fall back, and the offset amount to apply. An admin needs to configure this correctly, rather than just enabling chasTimezoneDstAdmin, whenever local DST rules change or the chassis is relocated to a region with different DST dates, since an outdated encoded rule here would cause the clock to shift on the wrong date. For US Eastern time, this object would encode a rule for the second Sunday in March at 02:00 and the first Sunday in November at 02:00 with a one-hour offset.
