Good idea, but doesn't seem to help:

    timestamp.secPastEpoch = 1366124582 - POSIX_TIME_AT_EPICS_EPOCH;
    timestamp.nsec = 0;
    epicsTimeToGMTM(&tm, &nsec, &timestamp);
    tm.tm_isdst = 0;
    epicsTimeFromTM(&utc, &tm, 0);
    epicsTimeToStrftime(cbuf, sizeof cbuf, "%F_%H:%M:%S", &utc);
    printf("%s\n", cbuf);
produces
    2013-04-16_16:03:02

But
date -u -r 1366124582

Hi Eric,

Perhaps force the isdst flag to 0 in between calls:

epicsTimeToGMTM(&tm, &nsec, &timestamp);
tm.tm_isdst = 0;
epicsTimeFromTM(&utc, &tm, 0);
