Converting RFC 2822 "timestamp" to timestampz
|
|
| Milen A. Radev 2005-10-27, 8:14 am |
| I have a RFC2822 timestamp (example: Thu, 21 Dec 2000 16:01:07 +0200).
I need to convert it to "timestampz" but I stumbled on the timezone
conversion. The code follows:
$timestamp = date( 'Y-m-d H:i:s O', strtotime( $rfc2822_timestamp) );
Unfortunately the supported formats for timezone in PHP and PostgreSQL
differs. Pgsql requires zone name or offset in the format "H:M"
(http://www.postgresql.org/docs/8.0/...-TIMEZONE-TABLE).
The "date" function in PHP (versions up to 5.0) supports the following
two formats: "Difference to Greenwich time (GMT) in hours. Example:
+0200" and "Timezone offset in seconds: -43200 through 43200".
Of course I could play a little bit with last number (converting it to
"hours:minutes") but it seems unnatural. Am I missing something?

The following works for me:
# select 'Thu, 21 Dec 2000 16:01:07 +0200'::timestamptz;
timestamptz

2000-12-21 06:01:07-08

You are so right! I was confused by another bug in my query to believe
that the RFC2822 format is unacceptable.
