| The first column is date-time. The default format is yyyy-mm-dd [HH:MM], where hour and minutes are necessary if the timestep is shorter than one day. The date-time is the beginning of the timestep. It is possible to use another date-time format: yyyymmdd[HHMM]. It is expected for all forcing files, if ''readformat 1'' is set in [[start:HYPE_file_reference:info.txt|info.txt]]. | The first column is date-time.

| - | For calibration of small model set-ups running time may be reduced by holding the forcing data in memory instead of reading the files for each time step.
