KB 232497. Official workaround: "The original time is still available by right-clicking the message, and then clicking Properties. The time shown in the message's properties is the e-mail header time recorded by the e-mail server; it is not affected."
Its been said that this problem will fix itself in three weeks time when the usual DST started. But remember, DST extends for an extra week, so you'll have one more week of
spam from the future -- unless of course you are using Thunderbird like myself, then this isn't an issue (or Outlook for that matter).
An associated poll has been created to see how many folks are affected by this. Cheerio.]]>
