Matrix ETERNITY NE System Manual 789
• Day: Select the day of the month - Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday
- when DST begins.
• Month: Select the month when DST beings (January-December).
• Change Time From: Select the time when DST will begin to change. The time mode is 24 hours, with
options from 00 to 23 hours and 00 to 59 minutes.
• To: Select the time to which the DST is advanced. The time mode is 24 hours, with options from 00 to
23 hours and 00 to 59 minutes.
• Now, go to the option 'Backward Time Adjustment' to set the time back (i.e. end DST and begin standard
time).
• Follow the same steps described above to set the day/date, month, hours and minutes except, here you
must set these parameters according to the time when DST ends.
• Click Submit to save your DST settings.
• SARVAM UCS gives you the flexibility to set the 'Forward DST Adjustment' according to Date-Month,
while the Backward DST Adjustment according to Day-Month. Similarly, the reverse is also possible,
i.e. Forward DST may be set according to Day-Month, while the Backward DST may be set as Date-
Month. This flexibility is particularly useful for setting DST of countries where the start of DST is defined
by date and month, e.g. First of April, but the end of DST is defined by Day and Month, such as the last
Sunday of October (as observed in Cuba).
• When the DST of a particular country starts or ends on the Last Sunday or any other day, for example,
the last Tuesday, last Friday of the month, always set the Ordinal Number as '5th'.
• Wherever time adjustments are made at 00:00 hours, use the previous date and set DST start time
(that is, "from" time) at 23:59 hrs.
• If you synchronize the RTC with the SNTP Server and the Date and Time changes, the DST will be
applicable as per the new Date and Time.
