I originally incorrectly posted my question to the
GENERAL list with the same subject.

As I indicated in my original post I am trying to
convert an binary timestamp (int64).

After further experimentation I have yet to find a
method to correctly convert the int64 value retrieved
from a query. 

I save 1970-01-01 00:00:00 and read it back expecting
the difference between postgres and unix epochs but
get different results each time. 

(After conversion to host byte order).

-946686612744257
-946684195712577
-946684196834881

I then tried using PGTYPEStimestamp_to_asc() just to
see what it does and get....

1969-12-31 23:07:28.818367
1969-12-31 23:38:40.464063
1969-12-31 23:52:03.009727

psql shows 1970-01-01 00:00:00

Using 2000-01-01 the minutes/seconds/fractional
seconds  varies as well. 

If request back dates formattea as strings, I get what
psql shows, the correct result. 

Why would pg returning inconsistent binary timestampo
results? 

Thanks
