I am modifying the time manager to allow longer timesteps (multi-month, annual or multi-year). However, I am not fixing everything right now.

Things I have found that need to be fixed in the future:

- determination of newhour in subroutine time_manager: I believe that this line:

if (ihour /= ihour_last) newhour = .true.

will not work for time steps that are multiples of a day

Also, I have not checked all of the code completely to be sure that things will work correctly for longer timesteps. In particular, I have not checked the code that determines stopping conditions: does any of this stop-related code implicitly assume timesteps shorter than about 1 month? Similarly for the time_to_do and time_to_start functions.
