CHAPTER 5: SETTINGS PRODUCT SETUP
M60 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL 5-113
5
The M60 maintains two times: local time and Universal Coordinated Time (UTC). Local time can be provided by IRIG-B
signals. UTC time is provided by SNTP servers.
The real-time clock (RTC) and time stamps reported in historical records and communication protocols can be incorrect if
the Local Time settings are not configured properly.
See the IRIG-B section in the Installation chapter for guidance on these settings when using an IRIG-B source that sets the
IRIG-B control bits according to IEEE Std 1344-1995.
LOCAL TIME OFFSET FROM UTC — Used to specify the local time zone offset from UTC (Greenwich Mean Time) in hours. Time
zones in the eastern hemisphere have positive values; time zones in the western hemisphere have negative values. A value
of zero causes the relay to use UTC for local time. This setting has two uses. When the system RTC is synchronized with a
communications protocol providing only local time or it is free-running, the offset setting is used to calculate UTC from the
local time these provide. When the RTC is synchronized with a communications protocol providing only UTC (such as PTP or
SNTP), the time offset setting is used to determine local time from the UTC provided. PTP
ALTERNATE_TIME_OFFSET_INDICATOR TLVs are not used to calculate local time.
DAYLIGHT SAVINGS TIME and DST — Can be used to allow the relay to follow the DST rules of the local time zone. Note that
when IRIG-B time synchronization is active, the local time in the IRIG-B signal contains any daylight savings time offset and
so the DST settings are ignored.
