[hylafax-users] Re: Y2K bug in xferfaxstats from hylafax 4.1beta2

[Lee Howard <faxguy@deanox.com>]

This patch doesn't apply to my version (4.1beta2-5)... here's the
appropriate section:

function cvtDateTime(s)
{
    yday = substr(s,7,2)
    if (yday < 70)
        yday += 30;
    else
        yday -= 70;
    yday = yday*365 + substr(s,4,2) - 1;
    mon = substr(s,1,2) + 0;
    for (i = 0; i < mon; i++)
        yday += daysInMonth[i];
    return yday*FULLDAY + cvtTime(substr(s,10) ":00");
}

Was this Y2K bug already fixed in this (although differently)?
