We use 2010R1RC5 in our products and now I discovered a bug. We are in the GMT+1 timezone and we use DST. Our etc/TZ file looks like this:
The DST to summer time was in last Sunday but the system clock still shows the winter time. I checked that the DST will change to summer time on the next Sunday. It means in this week our clock lates one hour.
I know it is Thursday now and I have to wait some days only. Our customers haven't discovered this bug yet.
I checked the changing in the future dates and it seems OK.
Maybe the problem caused by the leap year?
