+
+
+ The epoch_to_timestamp function converts
+ UNIX epoch timestamp (seconds from 1970-01-01 UTC) to timestamp
+ without time zone. The epoch_to_timestamptz
+ function accepts a double precision argument and returns
+ timestamp with time zone, allowing compatibility with
+ extract, which returns
+ double precision values.
+
+
+
+
+ epoch_to_timestamp(source)
+
+ source is an integer value
+ or expression. epoch_to_timestamp returns a value
+ of timestamp without time zone.
+
+
+
+
+ epoch_to_timestamptz(source)
+
+ source is a double precision value
+ or expression. (Values of integer are cast automatically.)
+ epoch_to_timestamptz returns a value of
+ timestamp with time zone.
