In WRFOUT file, if the timestep interval is not same, how to give in namelist.ARWpost

[anuradha]

When the time intervals (in seconds) are not uniform in the wrfout file, how to give in interval_seconds, in namelist.ARWpost.
I have given
&datetime
start_date = '2023-06-09_06:00:00',
end_date = '2023-06-11_06:00:02',
interval_seconds = 3600,
tacc = 0,
debug_level = 0,
/

It is giving error as
!!!!!!!!!!!!!!!!
ARWpost v3.1
!!!!!!!!!!!!!!!!

FOUND the following input files:
./wrfout_d02_2023-06-09_06:00:00
