What time is it??

[Knothead]

One day an engineer calls the dispatcher and asks him for the time.
The dispatcher responds by asking him what road he works for. The
engineer is a little pissed and snaps "What difference does that make?"

"Well," the dispatcher drawls, "if you work for the BN it's 2 pm; if
you work for the UP it is 1400; if you work for the Norfolk Southern or  CSX the
big hand is on the 12 and the little hand is on the 2; and if you
work for Amtrak it's Tuesday!"
