sntpc rc-service start doesn't support the run-once mode that the conf.d file advertises
* [root
sdaoden]# head –3 /etc/conf.d/sntpc
#
# Set time sync interval (in seconds) here.
# Setting SNTPC_INTERVAL to 0 will make sntp run once and just exit
- [root@sdaoden]# ps axu|grep sntp
6712 root 0:00 grep sntp - [root@sdaoden]# rc-service sntpc start
