Ignore my request. The solution is:
   ---------------------------
computeIfUptime() -------------------------------------

  select (EXTRACT(EPOCH from TIMESTAMP 'now') - EXTRACT(EPOCH from TIMESTAMP
'2005-10-18 17:00:00'))::integer

Subject: What Am I Doing Wrong?


I have been trying to subtract two timestamps from each other to determine
the difference between the two timestamps (current time and a past timestamp
called 'updated_time') IN SECONDS, but no luck.

The trouble I am having is getting the first timestamp, representing the
current time, to translate to seconds; have tried different commands (now(),
localtimestamp, current_timestamp, etc)

What am I doing wrong? Sample statement and error message is below:

                      ------------------------------------------

select EXTRACT(EPOCH from TIMESTAMP current_timestamp) - EXTRACT(EPOCH from
TIMESTAMP updated_time) ::integer

ERROR:  syntax error at or near "current_timestamp" at character 37
