// A Timestamp represents a point in time independent of any time zone

// nanosecond resolution in UTC Epoch time. It is encoded using the

// Proleptic Gregorian Calendar which extends the Gregorian calendar

|
// backwards to year one. It is encoded assuming all minutes are 60
|
|
// seconds long, i.e. leap seconds are "smeared" so that no leap second
|
|
// table is needed for interpretation. Range is from
|
|
// 0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z.

// Timestamp timestamp;

// timestamp.set_seconds(time(NULL));
|
|
// timestamp.set_nanos(0);

//
|
|
// struct timeval tv;
|
|
// gettimeofday(&tv, NULL);
|
|
//
|
|
// Timestamp timestamp;
