Hello,

we just found an error inside the date-time library.

I use "boost::posix_time::microsec_clock::local_time()" to get the actual
time.
When the microseconds overflow and a new second starts, the seconds don't get
incremented atomically together with the microseconds.

Is this a known bug?

My System:
        boost version 1.31.0
        Linux 2.6.3, SMP (Red Hat Enterprise)
        2x Intel Xeon HT

Some values of consecutive calls:
