While running the regression tests to investigate other issues, I noticed
a repeated failure that I had not seen before 7.1RC2. The timestamp
test now always fails. See attached for details.

Could this be a Day Light Savings issue? Or, a problem with 7.1RC2?

Thanks,
Jason

    Yes, I think daylight savings. Try again tomorrow.

    See
    http://www.postgresql.org/devel-corner/docs/postgres/regress.html#AEN14359

    Specifically:

    : Some of the queries in the "timestamp" test will fail if you run the
    : test on the day of a daylight-savings time changeover, or the day before
    : or after one. These queries assume that the intervals between midnight
    : yesterday, midnight today and midnight tomorrow are exactly twenty-four
    : hours -- which is wrong if daylight-savings time went into or out of
    : effect meanwhile.

    Thanks for the responses. The timestamp test ran without failures today.
