Gabor,
Thanks, that worked. However, is there is way to just get the time and not
have the date added? I assume the date is added since POSIX is based on
seconds since 1970. I can't seem to convert the POSIX value to Chron times(),
and Chron won't take fractional seconds. Are there other ways to deal with
just time and not date?
Thanks,
Tim
