示例1: main
//.........这里部分代码省略.........
//: the current wall clock time.
//:
//: 3 QoI: That consecutive values do not decrease (under normal
//: conditions).
//:
//: 4 QoI: The resolution of the real-time clock is < 1 second.
//
// Plan:
//: 1 Call 'nowRealtimeClock' and verify the value returned, when
//: treated as an interval from the Unix epoch, corresponds to a
//: possible wall clock time. (C-1)
//:
//: 2 Call 'nowRealtimeClock' and compare the value returned to an
//: oracle clock, i.e., the standard library function 'time'. (C-2)
//:
//: 3 Call 'nowRealtimeClock' in a loop for a couple seconds; verify
//: the results do not decrease between iterations, and that
//: increments of the clock are less than 1 second. (C-3..4)
//
// Testing:
// TimeInterval nowRealtimeClock();
