You seem a bit harsh and cynical ... did you register just so you could come here and be that way?
1) No. Not as designed. UTime was written many years before TTT was even written, and, as such, very few of the older projects have been upgraded for TTT. We thank you for your kind constructive idea though.
2) Can't be done from server. Clients can use convar "utime_enable <0|1>" to hide the hud.
Why would UTime, written totally to be independent of ULX, and I think, perhaps even independent of our library, ULib, be integrated by default into XGUI, a menu system written that requires ULib, and is made to control ULX?
It's not too much to wish for.
Learn Lua. Adding the checks (to ensure UTime was loaded) and creating a UTime tab would be a good learning project.
Then rather than coming and seeming hostile, you could come, join a great community, and contribute to it.
