Why is RWTime using a different default timezone than the one the date command uses?

Question

I normally get the same time but there is a host on which, when I run the following simple program:

int main()
{
    RWTime now;
    std::cout << now.asString() << "," << RWZone::local().timeZoneName() << std::endl;
}

I get output like this:

$> date && ./simple_program
Thu Jun 12 03:16:34 EST 2014
06/12/2014 04:16:34,EST

If the timezone is the same, how can they be producing different results? The date command is right, but the RWTime from simple program is one hour ahead of reality.

Answer 1

It would appear that your locale is using EST, not EDT, so the date program is returning a time an hour earlier than the actual time. RWZONE.local() appears to use daylight saving time, but reports the name of the time zone as EST, not EDT.
