Apparently DATE-OBS field is not being populated in fits files. I've heard this from another spectroscopist.

I have been using indi/kstars/ekos for several years for astro spectroscopy, where the platesolving camera via flip mirror is separate to the spectro camera which is never platesolving as it only sees the slit spectroscopy images through the spectrograph.

Not including DATE-OBS is a total deal breaker as the isis spectroscopic reduction software commonly used by amateur spectroscopist needs it.

Is there a particular reason why the new optical trains system does not populate this field of the fits header? When using indi for actual science not just pretty pictures, the actual observation date and time are essential information.
