I know its possible, but probably need a little work. for instance, when a player make a move in a live game, need to saved no only the move just done, but also what the clock was displaiing at that time. Once that database have saved this sort of information, would be quite easy to build a PGN with that info.
The main question is that fature its worth the "programming hassle" of not? Probably depend on how many of us would like that feature, so the more people sign for this request, the most likelly they will decide to implement it.
I'm one of those people that prefer playing slow games instead of those bullet one. Something like 30-0, 45-5 or 45-45. The slower the better. And once that game its finisced i usually download that PGN and analyze the game i played. During my analysis i would like to know how much it took me to make a certain move, in order to seen if i played too fast or too slow. So i would like to have this added feature.
Ist possible to have the PGN with commented the time used , or the time left (the same that clock its showing)?
1.d4 {time left: 44.30} Nf6 {time left: 45.30} 2.c4 ...
This little change will give a lot more infos during a post mortem analysis.
