 // A Timestamp represents a point in time independent of any time zone
 // or calendar, represented as seconds and fractions of seconds at
 // 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.
