installing ntp on routerboard v 4.9

I have a new routerboard 750 with v 4.9 routeros installed. I want to install ntp however,
the packages available are 4.10 and 3.x.

I assume I cannot install 4.10? I did ftp that version to the root directory of the router
however I deleted it as I was afraid the version number would not work.

How do I obtain version 4.9 of ntp? If I have the correct version do I just ftp it to the
root directory and reboot to install?

Thanks for any help.

Upgrade to v4.10 and use v4.10 NTP package.

That works! I had figured it out after I asked. Thanks again.
