Haven't seen it, but if people are reporting sudden hour offsets, on the first Monday in April, I'd bet on a DST implementation bug that hijacked the system clock on their servers.
This doesn't look like the sort of error you'd get with a free running clock.
I concur, about the one-hour shift anyway. The random garbage times aren't really likely either - jumps that large would tend to get the source rejected as a falseticker. It's a weird set of symptoms that rather looks as if they hit two different failure modes at once. Dunno.
