Tables on players Serverside and Clientside

[eNergizer]

Alright lets say I make a table on a player like this:
LocalPlayer().PvpTimeLeft = 60

Can LocalPlayer().PvpTimeLeft be accessed by the server via playerEntity.PvpTimeLeft ?
Can LocalPlayer().PvpTimeLeft be accessed by other client side scripts?

And lets say I make this on the server side.
ply.nextPvpSecond = CurTime()

Can ply.nextPvpSecond be accessed by clientside with LocalPlayer().nextPvpSecond ?
Can ply.nextPvpSecond be accessed by other server side scripts?

And this is all assuming that you access the same entity.
