Recent -current builds provide files with modification dates of zero

Hi all,

I've noticed that all the recent builds of -current on nyftp.netbsd.org
provide files with a modification date of zero. E.g.:

A recent netbsd-7 build:

[disciple@arcusix ~]$ tar tvzf kern-GENERIC.tgz 
-rwxr-xr-x root/wheel 17808252 2017-01-29 21:40 ./netbsd

A recent -current build:

[disciple@arcusix ~]$ tar tvzf kern-GENERIC.tgz 
-rwxr-xr-x root/wheel 21141528 1969-12-31 19:00 ./netbsd

Regards,

Dave
