tMin_ resets when an iteration has 0 us duration.

[rikba]

The timing class resets tMin_ when tMin_==0. I guess this was set because tMin_ initializes with 0 . However, it is well possible that during runtime a timing iteration will only last 0 micro seconds. Then tMin_ keeps resetting.

An easy fix would probably be to initialize tMin_(SIZE_MAX) or whatever the maximum size for this variable is.
