See

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.
