I am looking for an Epoch (bigint) to date/timestamp converter in MonetDB - something similar to unix_timestamp() in MySQL. 

I referred this page - https://www.monetdb.org/Documentation/SQLreference/Temporal and tried out a few functions, but it seems to work only with the existing Timestamp columns. 

Am I missing something here? 

I am using MonetDB Jan2014 release on a Mac OS-X.

Any help much appreciated.
