If you really do mean an EB2, then yes, you can do it via MMP writes just like any other location.
You can find all the addresses in Pac Manager.
So set your time in the controller, then take each part of the time (hh, mm, ss) and write them to the IP address and MMP address of the EB2.
I have to ask... what timing events are you doing on an EB2 such that it needs accurate time???
This is a really interesting question you have asked.....
