CORBA's time format comes from DCE. The number in it is the number of
100 nanosecond intervals since 15th October 1582. There's nothing in
omniORB that knows anything about that, but I happen to have a little
function that handles it:


# Number of seconds between Unix epoch and DCE epoch
UNIX_TO_UTC_OFFSET_SECS = 12219292800L

def convertToUnix(utc):
    """convertToUnix(dtime) -> time in Unix format"""

    sinceunix = utc - (UNIX_TO_UTC_OFFSET_SECS * 10000000)
    secs = sinceunix / 10000000.0
    return secs


The convertToUnix function converts the DCE time to Unix time as a
floating point value. You can then give it to standard things like
time.ctime() to convert it to a string.

Cheers,

Duncan.
