RF 433 Mhz on virtual pin doesn't want to send (with scheduling)

@Dmitriy regarding Time Input we have noticed the following anomaly:

unsigned int startseconds = (0 * 3600) + (0 * 60); // gives the expected result of zero

but with the Time Input set with a reset time of --/-- the result of the following calculation is 4294967280

unsigned int startseconds = (t.getStartHour() * 3600) + (t.getStartMinute() * 60);

This indicates with a reset time of --/-- the t.getStartHour() and or t.getStartMinute() is not zero.

What value / String does Blynk hold for t.getStartHour() and t.getStartMinute() with a time of --/-- ?
