Pani,

Giving us some data would help but to simply increment a date time value
here are two ways:

data one ;
dtstart = '1jun1990:12:00:00'dt;

dtend = intnx('second',dtstart,30) ;

dtend2 = dtstart + 30 ;

format dtstart dtend dtend2 datetime. ;
put dtstart= dtend= dtend2= ;
run ;

I have to construct a price series with  every 30 seconds (so i have to
keep the last price(record) before the 30 second cutoff and remove the
remaining)

I have date, time and other columns.

thanks
pani
