I have to say I am not really familiar with coding (and to my understanding the API of steamgifts is not publicly available), so I can't say I know. On the other hand, the information should be stored somewhere and given that there is a possibility to display starting time and when the giveaway was created (as well as the remaining time once the giveaway started) I would assume it won't actually be too difficult to implement this.

But like I said, I have little knowledge of coding (and cg might be attending more pressing issues), just wanted to know if I wasn't overlooking something (e.g. ESGST option as there are so many).

You're welcome.
