Again, no deep knowledge: Do you mean not the start/end of an image export, but of an image acquisition over time, like a satellite traversal creating a stitched image from individual fields acquired over minutes or maybe hours? I would have assumed GeoTIFF would have already considered this; have you ruled that out already?
If not extant yet, I guess the proper approach would be to register one or more custom TIFFtags; this has been problematic of late. Hey, Leonard@Adobe, if you see this, I’m still happy to help on the TIFFtag registry. W.
