Hi Nelson,

I had a similar problem with values returned from GsGetTimInfo() a few weeks
ago and it was driving me *guzNUTS* until I found the solution (in the manual
of all places :) ...

You need to initialize the graphics system with GsInitGraph() before using
GsGetTimInfo() - none of the 'Gs' graphics functions work correctly until
this is done! (see page 101 of Library Ref).

This should solve it.

Cheers!
