Last change on this file since 2480 was 2422, checked in by Ehouarn Millour, 9 years ago

Small modification in the way time and calendar are handled: Now all the time keeping is done in the physics and only the timestep is transfered from the dynamics to the physics. Due to changes in computations and roundoffs this will change reference bench results.
The implementation of this change in phymar is left as future work.
