[Boost-users] DateTime: Request for additional time_duration methods

time_duration in Boost 1.35.0 has an is_negative() method.

I need exactly the opposite:

time_duration td;
while (td.is_positive())
{
        // reduce td in some way
}

I am aware, that I can use td.ticks()>0, but since is_negative() already 
exists, it would be nice to have also the following methods for 
completeness and symmetry:

bool time_duration::is_positive() const
bool time_duration::is_zero() const

So for all non special value time_duration instances one of the above 
methods would return true, the other two false.

Best regards, Peter.
