/**
* A Timestamp represents a point in time independent of any time zone or local
* calendar, encoded as a count of seconds and fractions of seconds at
* nanosecond resolution. The count is relative to an epoch at UTC midnight on
* January 1, 1970, in the proleptic Gregorian calendar which extends the
* Gregorian calendar backwards to year one.
*
* All minutes are 60 seconds long. Leap seconds are "smeared" so that no leap
* second table is needed for interpretation, using a [24-hour linear
* smear](https://developers.google.com/time/smear).
*
* The 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](https://www.ietf.org/rfc/rfc3339.txt) date strings.
*
* # Examples
*
* 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 Java `Instant.now()`.
*
* Instant now = Instant.now();
*
* Timestamp timestamp =
* Timestamp.newBuilder().setSeconds(now.getEpochSecond())
* .setNanos(now.getNano()).build();
*
* Example 6: Compute Timestamp from current time in Python.
*
* timestamp = Timestamp()
* timestamp.GetCurrentTime()
*
* # JSON Mapping
*
* In JSON format, the Timestamp type is encoded as a string in the
* [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the
* format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z"
* where {year} is always expressed using four digits while {month}, {day},
* {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
* seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),
* are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
* is required. A proto3 JSON serializer should always use UTC (as indicated by
* "Z") when printing the Timestamp type and a proto3 JSON parser should be
* able to accept both UTC and other timezones (as indicated by an offset).
*
* For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past
* 01:30 UTC on January 15, 2017.
*
* In JavaScript, one can convert a Date object to this format using the
* standard
* [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)
* method. In Python, a standard `datetime.datetime` object can be converted
* to this format using
* [`strftime`](https://docs.python.org/2/library/time.html#time.strftime) with
* the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one can use
* the Joda Time's [`ISODateTimeFormat.dateTime()`](
* http://www.joda.org/joda-time/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime%2D%2D
* ) to obtain a formatter capable of generating timestamps in this format.
