Thanks a lot for the suggestion. It worked out perfectly.
But, I still have a query. Is it necessary to fillin, or would it be
fine to allow the time series variable with gaps, say, to estimate
SUR? I need to know about this because, though it's implicit that the
observations for which data is not available should have been zero,
I'm reluctant to do this, as it could as well have been because of
missing data!

1. Given existing variables year and month,
. gen newdate=(year-1960)*12+month-1
. format newdate %tm

2. I assume you mean panel, i.e. you want the initial value for some
variable, say agehead, for each household (each cross-section means
looking over all households at a given point in time), and I assume
you have a household ID.
. bys hhid (newdate): gen init_agehead=agehead[1]

See -fillin- for  how to fill in the missing zero values you describe
in the first paragraph below.
