--- unixdate
--- Routines to convert int4 (Unix system time) to datetime
---  and int4 (delta time in seconds) to timespan
---
--- Thomas Lockhart (lockhart@alumni.caltech.edu)
--- 1997-11-25
---
--- This cheats and reuses existing code in the standard package.
--- Can not include this directly because built-in functions are optimized
---  into a cache and the duplicate function names abstime_datetime() and
---  reltime_timespan() would result in duplicate constants.
---
--- This works with Postgres v6.2 and higher.
