[Eeglablist] Timewarp: re-epoch or adjust desired latencies

[Makoto Miyakoshi]

Dear Fiorenzo,

Could you share your recent experience with timewarp option with him?
Unfortunately I haven't used it myself.

Ramon, Ole is in your position in TUB. I appreciate your support for him.
I've heard timewarp option is either unstable or limited to use somehow,
but for the mobi research it will be important.

Makoto
