//
// The Timestamp message represents a timestamp,
// an instant in time since the Unix epoch (January 1st, 1970).
//
// # Conversion to a Go Time
//
// The AsTime method can be used to convert a Timestamp message to a
// standard Go time.Time value in UTC:
//
//	t := ts.AsTime()
//	... // make use of t as a time.Time
//
// Converting to a time.Time is a common operation so that the extensive
// set of time-based operations provided by the time package can be leveraged.
// See https://golang.org/pkg/time for more information.
//
// The AsTime method performs the conversion on a best-effort basis. Timestamps
// with denormal values (e.g., nanoseconds beyond 0 and 99999999, inclusive)
// are normalized during the conversion to a time.Time. To manually check for
// invalid Timestamps per the documented limitations in timestamp.proto,
// additionally call the CheckValid method:
//
//	if err := ts.CheckValid(); err != nil {
//		... // handle error
//	}
//
// # Conversion from a Go Time
//
// The timestamppb.New function can be used to construct a Timestamp message
// from a standard Go time.Time value:
//
//	ts := timestamppb.New(t)
//	... // make use of ts as a *timestamppb.Timestamp
//
// In order to construct a Timestamp representing the current time, use Now:
//
//	ts := timestamppb.Now()
//	... // make use of ts as a *timestamppb.Timestamp

// 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://joda-time.sourceforge.net/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime()
// ) to obtain a formatter capable of generating timestamps in this format.
