flexfax: y2k problem in faxcron/recvstats/xferstats

["Frans E. van Dorsselaer" <frans@bia-bv.demon.nl>]

Hello,

I use hylafax 4.0pl2 on Suse Linux 6.1, but the problem
appears to be present in the current CVS as well.
Since 1/1/2000 faxcron reports _all_ faxes ever sent in
the receive stats, transmission stats, and error log report.

The receive/transmit stats are done in scripts called
recvstats and xferstats respectively, I fixed those (patch attached).
The problem is due to calculation of the age based on
YY * 365 + ..., where YY is a 2-digit year representation.
Fix includes YY < 70 check.

The error reports are filtered from faxcron itself, using
awk.  I'm not good at awk, and I haven't tracked down the
problem further.

Bye,

Frans van Dorsselaer
