Are cache dates always the same at different data centers?

Hi. When asking: "When was the last time Google has spidered a page" for a page for which you don't have access to the logfiles, you normally have a look at the google-cache of the page.

You get querys like http://209.85.135.104/search?q=cache:[SomeCode]:URL, so I was wondering if every datacenter/Google-IP gives you the same value for the cache-date, or if some datacenters could be more recent then others.

Hi,
to my best knowledge the results may be slightly different for each datacenter, varying a day or two. Same goes for SERPs, toolbar updates etc.
