White screen admin login

 I can not login to admin.  I get a white screen and 500 error.

I ran update and got this

encoded file /usr/local/cwpsrv/htdocs/resources/admin/include/cron.php has expired

can I simply copy cron.php from my other install to fix the problem?

http://myip gives me the standard http test page.  All websites work normal.

I managed to change server time and ran update.  Update started by time out.
