If you know (or can look up) the number of hours difference, you would simply add or subtract the equivalent number of seconds from the local time to get EST.

I want to convert the local datetime variable to one in EST. Does anyone know of a SAS function or macro that can accomplish this? <BR /> <BR /> Thanks!<BR /> <BR /> Rebecca Fri, 24 Jul 2009 18:46:06 GMT https://communities.sas.com/t5/SAS-Programming/Time-Zone-Conversions/m-p/58525#M12676 rrr 2009-07-24T18:46:06Z https://communities.sas.com/t5/SAS-Programming/Time-Zone-Conversions/m-p/58526#M12677 SAS Date Times are simply seconds.
