When in doubt, resort to the free NCAR's NCL language for this fix:

a = addfile("file.nc","r") ; read in file
var = a->var ; let's say var is (time, lat, lon)
var!0 = "time"
Time = (/0,1,2,3,4,5,6,7,8,9,10/) ; or Time = ispan(0,10,1) or... Time
= <some string>
var&time = Time
.
<snip>
.
;write out to netcdf file
b = addfile("out_file.nc","c")
b->var=var

There are also other time fixes one may do.
