**Jen**, Tuesday, December 7, 2010 at 11:24pmRight. So what's 120 minutes from 3:00?

**Reiny**, Tuesday, December 7, 2010 at 11:24pmfirst device: 8 16 24 .... 120

2nd device : 10 20 30 ... 120

3rd device: 12 24 36 ... 120

so 120 minutes from now they coincide

120 min = 2 hours

so at 5:00 all 3 will peep at the same time
