// The following requirement is tested:
// If value returning functions are called in receiving communication operations (in templates, template fields,
// in-line templates, or as actual parameters), in guards or events of alt statements or altsteps (see clause 20.2),
// or in initializations of altstep local definitions (see clause 16.2), the following operations shall not be
// used in functions called in the cases specified above, in order to avoid side effects that cause changing the
// state of the component or the actual snapshot and to prevent different results of subsequent evaluations
// on an unchanged snapshot:
// d) All timer operations, i.e. start (timer), stop (timer), running (timer), read, timeout (see notes 4 and 6).
