The following snippet seems to generate non monotonic local_date.
I'm using boost 1.55 on linux.
#include
#include
int main() {
const boost::local_time::time_zone_ptr theTimeZone(
new boost::local_time::posix_time_zone(
"CET+01CEST+01,M3.5.0/02:00,M10.5.0/03:00")
);
boost::local_time::local_date_time myOldValue(
boost::local_time::local_microsec_clock::local_time(theTimeZone));
for (size_t i = 0; ; ++i) {
const boost::local_time::local_date_time myLocalTime =
boost::local_time::local_microsec_clock::local_time(theTimeZone);
if (myLocalTime < myOldValue) {
std::cout << myOldValue << std::endl;
std::cout << myLocalTime << std::endl;
std::cout << boost::local_time::local_microsec_clock::local_time(theTimeZone) << std::endl;
std::cout << "====================" << std::endl;
}
myOldValue = myLocalTime;
}
}
As you can see the program is not supposed to print nothing ever,
however this is what I'm getting:
2014-Jul-31 00:24:56.005625 CEST
2014-Jul-31 00:24:55.005631 CEST
2014-Jul-31 00:24:56.005946 CEST
====================
2014-Jul-31 00:24:58.005625 CEST
2014-Jul-31 00:24:57.005629 CEST
2014-Jul-31 00:24:58.005824 CEST
====================
2014-Jul-31 00:25:02.005624 CEST
2014-Jul-31 00:25:01.005628 CEST
2014-Jul-31 00:25:02.005838 CEST
====================
2014-Jul-31 00:25:04.005625 CEST
2014-Jul-31 00:25:03.005630 CEST
2014-Jul-31 00:25:04.005826 CEST
====================
2014-Jul-31 00:25:06.005624 CEST
2014-Jul-31 00:25:05.005633 CEST
2014-Jul-31 00:25:06.005853 CEST
====================
2014-Jul-31 00:25:07.005625 CEST
2014-Jul-31 00:25:06.005631 CEST
2014-Jul-31 00:25:07.005846 CEST
====================
2014-Jul-31 00:25:12.005625 CEST
2014-Jul-31 00:25:11.005631 CEST
2014-Jul-31 00:25:12.005822 CEST
====================
as you can see when the local_date is near 0.005631 second fraction it
goes back of one second and then forward again on the following call.
Am I missing something ?
