As a quick suggestion, check the SES time by making an HTTP request to SES (e.g. wget -S ""), and compare to your server's time. Update the server's time (or use NTP if you aren't already) and see if the problem resolves itself. – cyberx86 Oct 31 '12 at 13:19
Britain (and probably other countries) switched over to winter time at the same day your error started happening and the error says that the time is more than 300 seconds wrong. I would vote for that being the root cause. – Ladadadada Oct 31 '12 at 13:23
Thanks for the valuable comments.I will check. – Sujathan R Oct 31 '12 at 13:36
Did you ever find the cause of this? I use SES and am curious in case I ever ran into the same. – Nathan V Nov 28 '12 at 14:49
