Choose some widget in your GUI to generate the timer event. With

widget_control, id, timer=x

you will generate a timer event in that widget in x seconds. Note that
this happens only once, so for a continuous timer you have to include
this line of code again in the event handler itself.

To distinguish the timer event from other events: The most simple thing
is to choose a widget which otherwise doesn't generate events, like a
label widget. Otherwise, you have to check the event structure name in
the event handler for 'WIDGET_TIMER'.

Check the IDL reference for the TIMER keyword to WIDGET_CONTROL for more
information, or go to Programming in IDL -> Creating Graphical User
Interfaces -> Widget Application Techniques.
