building stable binaries

[Michael A Endsley]

I have been tracking stable and started rebuilding my system last night.
I let the system rebuild the kernel during the night and then I started
rebuilding the binaries this morning.
Here is the the end (with error) of the binary build before it quit:

checking whether build environment is sane... configure: error: newly
created file is older than distributed files!
Check your system clock
*** Error code 1

Stop in /usr/src/gnu/usr.bin/binutils/obj (line 17880 of Makefile).
*** Error code 1

Stop in /usr/src/gnu/usr.bin/binutils.
*** Error code 1

Stop in /usr/src/include (line 82 of Makefile).
*** Error code 1

Stop in /usr/src (line 73 of Makefile).


I typed "date" while the binaries were building to see how long it would
take (normally 3 hrs or so):
# date
Wed Feb 15 08:25:27 MST 2006



How do I fix the "newly created file is older than distributed files!"?
Thanks.
Mike
