You could try to define a time axis with the right interval using
define axis /t0=... /t=... my_time_axis
and then do something like
let my_new_var = my_old_var[gt=my_time_axis]
or
let my_new_var = my_old_var[gt=my_time_axis@asn]
(provided the time interval and start of the time axis is equal)
I'm not certain if this would work, but I think it should. If you
define a time axis like that it should become UNLIMITED, and you
should be able to regrid your data to the new axis quite easily.
