ROSS doesn't clearly indicate when g_tw_ts_end has been hit
The g_tw_ts_end variable sets a cap on the global timestamp of the simulation, at which point the simulation will stop running.
There is no clear indication in the output that this has happened however (or I am overlooking it if it is there). This causes confusion if the user expects the simulation to normally end by completing all pending events but it accidentally hits g_tw_ts_end instead.
