While using Amazon Simple Email Service, sometimes we encounter this error message:
” AWS Error Code: RequestExpired, AWS Error Message: Request timestamp: Sun, 13 Mar 2011 06:10:27 GMT expired. It must be within 300 secs/ of server time.”
This error probably means that Amazon SES time differs from your system clock time. If you’re using the command-line tools then you may need to adjust your system clock to match Amazon SES’s clock, which is synchronized with UTC.
If you’re using a linux system try this:
[email@example.com ~]# yum install ntpdate
# /usr/sbin/ntpdate 0.north-america.pool.ntp.org 1.north-america.pool.ntp.org 2.north-america.pool.ntp.org 3.north-america.pool.ntp.org
Now you can easily send emails using SES.
