need help settining time scale

Hi, I'm using Gaussian functions to fit points. After the fit, however, the xo parameter is not in time scale (hh:mm) like the abscissa axis but it is a number (44499 ± 86.9) that I don't understand. How to get xo in terms of hours?

Can you help me?

Use Secs2Time() for this:

print Secs2Time(44199,3), "±", Secs2Time(86.9,3)
