Here is how to change timezone setting in your RDS instance

1, connect your RDS instance as root.
[user@ec2 ~]$ mysql -u root -p -h xxxxxx.yyyyyy.zzzzzz.rds.amazonaws.com

2. Change the timezone setting.
mysql> DELIMITER |
mysql> CREATE PROCEDURE mysql.`set_PST`()
    -> IF NOT (POSITION('rdsadmin@' IN CURRENT_USER()) = 1) THEN
    ->    SET SESSION time_zone = 'America/Los_Angeles';
    -> END IF |
mysql> DELIMITER ;

3. Create parameter group
find init_connect parameter and input 'CALL set_PST'. Then save changes.

mysql> GRANT EXECUTE ON PROCEDURE mysql.set_PST TO 'username'@'hostname';

サイボウズガルーン v4.0.1、パッケージ版URLからクラウド版URLのリダイレクト

I figured out how to redirect web pages on Cybozu Garoon package edition to their cloud edition.
work as root user.

cd /var/www/cgi-bin/cbgrn/
mv grn.cgi grn.cgi.org
vi grn.cgi
write redirect script like following. then save it.

#!/usr/bin/perl

$uri = $ENV{'REQUEST_URI'};

my @param = split('grn.cgi',$uri);

$rdrURL =  "Location: https://xxxxxx.cybozu.com/g/$param[1]\n\n";

print $rdrURL;

exit;

chmod 755 grn.cgi
chown apache:root grn.cgi

That's it! Test the redirection.
