Many times I will check my SEPM console and see multiple PC's/Server that are out of date. The reason why they are not up to date is because the SEPM hasn't gone out to pick up the most current definitions. There is a random time where it does this and the SEPM admin had no control over the time. I think it would be a good idea to allow an admin to customize and even schedule it at time we designate.
Thank you.
