When EPMU = Y and MFRMT = C37.118, IRIGC is forced to C37.118.
IRIG-B Control Bits Definition (None, C37.118) None

All data, reports, and commands from the relay are stored and displayed in local time, referenced
to an internal UTC master clock. Use the UTCOFF setting to specify the time offset from UTC
time reference with respect to the relay location. (The only data still displayed in UTC time is
streaming synchrophasor and IEC 61850 data.)
Offset From UTC to Local Time (–15.5 to 15.5) –8
BEG_DST

c
The BEG_DST (and END_DST) daylight-saving time setting consists of four fields or OFF:
hh = local time hour (0–23); defines when daylight-saving time begins.
n = the week of the month when daylight-saving time begins (1–3, L); occurs in either the 1st, 2nd,
3rd, or last week of the month.
d = day of week (1–7); Sunday is the first day of the week.
mm = month (1–12).
OFF = hides the daylight-saving time settings.
Begin DST (hh, n, d, mm, or OFF) “2, 2, 1, 3”
END_DST End DST (hh, n, d, mm) “2, 1, 1, 11”
