Human_Time: Load CRNO, Endtime as Epoch, Timestamp(RangeSum('01/01/1970',Starttime/86400)) as Starttime, Timestamp(RangeSum('01/01/1970',Endtime/86400)) as Endtime, CI Resident Epoch;
Drop Table Epoch;
Above I'm converting Epoch to Timestamp. Epoch/86400 results in number of days. I did use 01/01/1970 considering the epoch definition (The Unix epoch (or Unix time or POSIX time or Unix timestamp) is the number of seconds that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap seconds (in ISO 8601: 1970-01-01T00:00:00Z). Literally speaking the epoch is Unix time 0 (midnight 1/1/1970), but 'epoch' is often used as a synonym for 'Unix time'. Many Unix systems store epoch dates as a signed 32-bit integer, which might cause problems on January 19, 2038 (known as the Year 2038 problem or Y2038). ).
