A lot of phones get their time from the telco, whose base stations are very 
well synchronised with each other but not always with that place in 
Greenwich.

But perhaps it's still reasonable to rely on correctness. If E-Plus is off 
(IIRC it was off by ~90 seconds when I was a customer) its customers either 
cannot undo send and/or can undo for 120 seconds rather than 30. Having 
that happen to a few people may be an acceptable price to pay for API 
simplicity. There are fewer than 1000 network operators, most of those 
<1000 clocks are correct to within a second or two, and the consequences of 
the errors seem minor.
