Manually generating obs_epoch.nc file within WRF-DART Tutorial fails

[braczka]

Describe the bug

1. List the steps someone needs to take to reproduce the bug.
   Perform the WRF-DART Tutorial. Within the optional section execute ./obs_seq_to_netcdf.

2. What was the expected outcome? Expectation was to generate obs_epoch_001.nc file similar to how the WRF scripting generates obs_epoch_029.nc automatically within obs_diag.csh script.

3. What actually happened?

obs_seq_to_netcdf fails

Error Message

 ERROR FROM:
  source : schedule_mod.f90
  routine: set_regular_schedule
  message:  schedule_nml:bin interval must be >= bin width

Fix is to set input.nml to:

&schedule_nml
   calendar        = 'Gregorian',
   first_bin_start =  1601, 1, 1, 0, 0, 0,
   first_bin_end   =  2999, 1, 1, 0, 0, 0,
   last_bin_end    =  2999, 1, 1, 0, 0, 0,
   bin_interval_days    = 1000000,
   bin_interval_seconds = 0,
   max_num_bins         = 1000,
   print_table          = .true.
   /
