Public bug reported:
Here in Seattle, on April 13, we're in daylight savings time. I've
noticed since DST started that log files created by Java applications
are an hour behind. I figured it had something to do with daylight
savings time. Non-Java applications do not display this symptom.
If it matters, here's the output of "java -version":
java version "1.6.0_10"
Java(TM) SE Runtime Environment (build 1.6.0_10-b33)
Java HotSpot(TM) Client VM (build 11.0-b15, mixed mode, sharing)
I wrote a small test application that prints out relevant information
about daylight savings time. I'll attach the test code, but the output
it produces follows this. You'll see that as of today, it thinks DST is
not in effect. It also shows that it thinks DST starts on April 26, and
ends on October 25, which is not correct.
