DST can be enabled and configured using this command. When enabled this will adjust
the system clock to comply with any DST requirement. DST adjustment effects system
time for both manually configured time and time set using SNTP service.
disable − Disable the DST seasonal time adjustment for the Switch.
repeating − Using repeating mode will enable DST seasonal time adjustment. Repeating
mode requires that the DST beginning and ending date be specified using a formula. For
example, specify to begin DST on Saturday during the second week of April and end DST
on Sunday during the last week of October.
annual − Using annual mode will enable DST seasonal time adjustment. Annual mode
requires that the DST beginning and ending date be specified concisely. For example,
specify to begin DST on April 3 and end DST on October 14.
s_week − Configure the week of the month in which DST begins.
• <start_week 1-4,last> − The number of the week during the month in which DST
begins where 1 is the first week, 2 is the second week and so on, last is the last
week of the month.
e_week - Configure the week of the month in which DST ends.
• <end_week 1-4,last> − The number of the week during the month in which DST
ends where 1 is the first week, 2 is the second week and so on, last is the last
week of the month.
s_day – Configure the day of the week in which DST begins.
• <start_day sun-sat> − The day of the week in which DST begins expressed using
a three character abbreviation (sun, mon, tue, wed, thu, fri, sat)
e_day − Configure the day of the week in which DST ends.
• <end_day sun-sat> − The day of the week in which DST ends expressed using a
three character abbreviation (sun, mon, tue, wed, thu, fri, sat)

• <start_mth 1-12> − The month to begin DST expressed as a number.
e_mth − Configure the month in which DST ends.
• <end_mth 1-12> − The month to end DST expressed as a number.
