Fault Reports - GE D30 Instruction Manual

PRODUCT SETUP
The D30 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 timestamps reported in historical records and communication protocols can be incorrect if
the Local Time settings are not configured properly.
LOCAL TIME OFFSET FROM UTC
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. When a communications protocol other
than PTP provides UTC to local time offset (meaning IRIG-B), that offset is used instead of the local time and daylight time
settings.

DAYLIGHT SAVINGS TIME
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.
