I'd like to see it output "2013-12-20T15:53:39.098204-08" so
it's interchangeable with more systems.
Actually, "2013-12-20T15:53:39.44553-08:00" would be ideal.
I dug into the docs some more, and I found this at
http://www.postgresql.org/docs/9.3/static/datatype-datetime.html:
"Note: ISO 8601 specifies the use of uppercase letter T to separate
the date and time.PostgreSQL accepts that format on input, but on
output it uses a space rather than T, as shown above. This is for
readability and for consistency with RFC 3339 as well as some other
database systems."
So I looked up RFC 3339 (http://www.ietf.org/rfc/rfc3339.txt) and
read: "NOTE: ISO 8601 defines date and time separated by "T".
Applications using this syntax may choose, for the sake
of readability, to specify a full-date and full-time separated
by (say) a space character."
Doesn't seem like including the 'T' separator would be inconsistent
with RFC 3399?
I'm sending the output of to_json(now()) to web browsers. Most
browsers aren't able to parse the date strings if they are missing the
'T' separator. If datetime strings could include the 'T' time
separator and the full timezone, that would make generating json that
worked with web browsers much simpler.

http://en.wikipedia.org/wiki/ISO_8601#Combined_date_and_time_representations
says 'T' can be omitted "by mutual agreement".
I'm working with javascript/json systems that expect the 'T'
to be there however, so there's no mutual agreement happening.
Thoughts? I know I can hack around it by specifying my own
date format, but I'd really like to be able to use row_to_json
and other functions without specifying custom date formats
everywhere.
Joe
Should there be a boolean option "isTeaTime" - for inserting a "T' in
the output?
Cheers,
