hi
I have a time series, X. the range is, let say, 1990 - 2000.
The frequency is quarters.
I would like to create a new series that depends on the date of X and the date of X. something like
Y=X+(year of X).

how can I refer to the year  / quarter in which the sample was taken?

thanks in advance,

Raz.
