Tying to add Lokai's Skill System, issue with TickCount

[Archaaz]

I am attempting to add Lokai's Skill System to my RunUO server, but have run into an issue involving TickCount. Apparently this was added to the ServUO Core.

I receive the following errors when compiling:

I replaced Core.TickCount with DateTime.Now, and reduce the errors:

I am wondering if someone might be so generous as to tell me how I can replace this to make it work on my RunUO server, and whether or not changing Core.TickCount to DateTime.Now will cause any unforseen errors? Many thanks in advance!
