Mismatch between model_basis_time read and validity time read

Hi there,

I met a problem in running a UKCA suite (u-de518), see below:
? Error code: 10
? Error from routine: INITTIME
? Error message:
? Mismatch between model_basis_time read from namelist and validity time read
? from dump fixed header.
?
? model_basis_time = 2019 9 1 0 0 0
? fixhd validity time = 2015 9 1 0 0 0
?
? If this is intentional disable this check by setting all elements of
? namelist:nlstcall=model_basis_time to zero. Otherwise make adjustments to
? either the namelist or dump to ensure that these two values match.
?
? Please note, that if it is valid to do so for your job setup, you may change
? the validity time of the dump using the reconfiguration namelist variables:
? * namelist:headers=i_override_date_time
? * namelist:headers=new_date_time
?
? Please see the metadata help text associated with these two variables for
? more information.
? Error from processor: 4
? Error number: 63

I could not find where I introduced the year “2019”, as “the model basis time” in the suite was set to “2015” (rather than 2019). Anywhere that I could check to see what cause the problem? Thanks!

Cheers,
Xin
