// 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.
// By restricting to that range, we ensure that we can convert to
// and from  RFC 3339 date strings.
// See [https://www.ietf.org/rfc/rfc3339.txt](https://www.ietf.org/rfc/rfc3339.txt).
//
// Example 1: Compute Timestamp from POSIX `time()`.
//
//     Timestamp timestamp;
//     timestamp.set_seconds(time(NULL));
//     timestamp.set_nanos(0);
//
// Example 2: Compute Timestamp from POSIX `gettimeofday()`.
//
//     struct timeval tv;
//     gettimeofday(&tv, NULL);
//
//     Timestamp timestamp;
//     timestamp.set_seconds(tv.tv_sec);
//     timestamp.set_nanos(tv.tv_usec * 1000);
//
// Example 3: Compute Timestamp from Win32 `GetSystemTimeAsFileTime()`.
//
//     FILETIME ft;
//     GetSystemTimeAsFileTime(&ft);
//     UINT64 ticks = (((UINT64)ft.dwHighDateTime) << 32) | ft.dwLowDateTime;
//
//     // A Windows tick is 100 nanoseconds. Windows epoch 1601-01-01T00:00:00Z
//     // is 11644473600 seconds before Unix epoch 1970-01-01T00:00:00Z.
//     Timestamp timestamp;
//     timestamp.set_seconds((INT64) ((ticks / 10000000) - 11644473600LL));
//     timestamp.set_nanos((INT32) ((ticks % 10000000) * 100));
//
// Example 4: Compute Timestamp from Java `System.currentTimeMillis()`.
//
//     long millis = System.currentTimeMillis();
//
//     Timestamp timestamp = Timestamp.newBuilder().setSeconds(millis / 1000)
//         .setNanos((int) ((millis % 1000) * 1000000)).build();
//
//
// Example 5: Compute Timestamp from current time in Python.
//
//     now = time.time()
//     seconds = int(now)
//     nanos = int((now - seconds) * 10**9)
//     timestamp = Timestamp(seconds=seconds, nanos=nanos)
