Is it possible to have acquisition time variable for geostationary images like goes and himawari?

Hi.

As it takes almost 10 minutes (at best case) for a geostationary full disk image to be taken, it might be important for some applications to know the exact time acquisition for the region of interest.

Wanted to know if it is possible to have such layer in Satpy.

Thanks in advance

I found that time information for some scanlines is available in the metadata of the HRIT format (Himawari data), but I could not find anything similar for GOES ABI.

One simple idea is to interpolate the time linearly, but that does not seem to be accurate since ABI is not a full-disk image over the entire 10 minutes.

I think another idea would be to implement scan mode timeline if possible.

I would appreciate any suggestions.
