It's trivial. All you have to do is offset by the difference in starting
MJD is usually printed as an integer rather than year-month-day format. (My
sample is tiny so that could easily be bogus.)
This is what I use to make log files similar to what ntpd writes.
#define MJD_1970 40587 /* MJD for 1 Jan 1970 */
struct timeval stop;
day = stop.tv_sec / 86400 + MJD_1970;
sec = stop.tv_sec % 86400;
msec = stop.tv_usec / 1000;
printf(file, "%d %d.%03d", day, sec, msec);
These are my opinions, not necessarily my employer's. I hate spam.
