I noticed that the interval between two time points in my result output file is not 1 hour but 59 minutes and 24 seconds.
Is it possible to change this ? The history_interval property in namelist.input is set to 60 minutes.
Can you attach your full namelist.input file, along with one of your run-time logs (e.g., rsl.out.0000)? Thanks!
Can you try to add, to the &time_control section of the namelist:
adjust_output_times = .true.
and see if that helps. If not, please attach your simulation output file (e.g., rsl.out.0000). Thanks!
