For some websites.
Noticed : Google's cache of website-URL as retrieved on G-cache-time(D/M/Y/h/m/s) GMT
Is the G-cache-time normal if it shows a time but months ago or weeks ago.
eg: today is "6 Mar 2007" but the G-cache-time retrieved on "6 Jan 2007 02:28:59 GMT"

Does IT matter?
Why it happened?
Any Possible reasons or indications for being site-cache delayed?

Thanks.
