export time fails?

Hi. I used the export time feature. For this game works:
http://en.lichess.org/analyse/kdfpdn38/export?time=1
1. e4 {0} e5 {0} 2. Nf3 {2} f5 ...

but for this no:
http://en.lichess.org/analyse/990s1jl6/export?time=1
1. e4 e5 2. c3 f6 3. d4 d6 4. Nf3 ...

What is the problem?

yep, the time is only available for rated games.

Why? Is complicated (in programming level) allow the same for non rated games?

well I don't think so... but the move time was implemented to help detecting engines. It makes less sense in unrated games.

I use time to study my/adversary move times - it's nice.
