It should be local time.

Me too :)

It is a one line fix in datetime.c, on or about line 918. It needs a
"tmask = 0;" for the new DTK_ISO_TIME case so that the "feature bitmask"
is not altered by the "T" in the string. When it is altered, it thinks
that a time zone was already specified, so does not try to determine
one.

Before:

thomas=# select timestamp '2001-10-19T16:47';
------------------------
2001-10-19 09:47:00-07

After:

thomas=# select timestamp '2001-10-19T16:47';
------------------------
2001-10-19 16:47:00-07

I have patches...
