Cron Problems

[Mark Gregson]

	I have a small problem with cron on a Xenix 286 system running
	system V version 2.2.1. 
	At present I have a job in the file /usr/spool/cron/crontabs/root
	that has this entry 0 23 * * * /usr/markg/news.
	The idea behind this entry is to have the program news run at
	2300 hours or 11pm, which does happen. However, this program 
	also executes at 500 hours or 5am?? Which it is not supposed to
	do. Can anyone please tell me why this type of error would 
	possibly occur??
