[TRNSYS-users] Problems with Timestep

Dear Trnsys Users,
 
I'm having a problem while I try to run a simulation with a 0.01h time
step. My radiation data is in 1 minute intervals and therefore my time
step has to be smaller than that. I chose 0.01h, but I get the following
error when I try to run the simulation
 
* START, STOP and STEP

  CONSTANTS   3
     START=4037
     STOP=4080
     STEP=.01
 * User defined CONSTANTS

 *SIMULATION Start time End time   Time step

  SIMULATION         4.037E+03    4.080E+03    1.000E-02
 
 ***** ERROR *****        TRNSYS ERROR # 203
 THE SIMULATION START TIME MUST BE AN INTEGER MULTIPLE OF THE
 SIMULATION TIMESTEP. CHECK SIMULATION STATEMENT.
 
I don't get it 4037/0.01=403700, which is an Integer multiple of the
timestep. 
 
Any help?
 
Thanks,
Juan
