4/// A Timestamp represents a point in time independent of any time zone or local
5/// calendar, encoded as a count of seconds and fractions of seconds at
6/// nanosecond resolution. The count is relative to an epoch at UTC midnight on
7/// January 1, 1970, in the proleptic Gregorian calendar which extends the
8/// Gregorian calendar backwards to year one.
9///
10/// All minutes are 60 seconds long. Leap seconds are "smeared" so that no leap
11/// second table is needed for interpretation, using a \[24-hour linear
12/// smear\](<https://developers.google.com/time/smear>).
13///
14/// The range is from 0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z. By
15/// restricting to that range, we ensure that we can convert to and from \[RFC
16/// 3339\](<https://www.ietf.org/rfc/rfc3339.txt>) date strings.
17///
18/// # Examples
19///
20/// Example 1: Compute Timestamp from POSIX `time()`.
21///
22/// ```text
23/// Timestamp timestamp;
24/// timestamp.set_seconds(time(NULL));
25/// timestamp.set_nanos(0);
26/// ```
27///
28/// Example 2: Compute Timestamp from POSIX `gettimeofday()`.
29///
30/// ```text
31/// struct timeval tv;
32/// gettimeofday(&tv, NULL);
33///
34/// Timestamp timestamp;
35/// timestamp.set_seconds(tv.tv_sec);
36/// timestamp.set_nanos(tv.tv_usec * 1000);
37/// ```
38///
39/// Example 3: Compute Timestamp from Win32 `GetSystemTimeAsFileTime()`.
40///
41/// ```text
42/// FILETIME ft;
43/// GetSystemTimeAsFileTime(&ft);
44/// UINT64 ticks = (((UINT64)ft.dwHighDateTime) << 32) | ft.dwLowDateTime;
45///
46/// // A Windows tick is 100 nanoseconds. Windows epoch 1601-01-01T00:00:00Z
47/// // is 11644473600 seconds before Unix epoch 1970-01-01T00:00:00Z.
48/// Timestamp timestamp;
49/// timestamp.set_seconds((INT64) ((ticks / 10000000) - 11644473600LL));
50/// timestamp.set_nanos((INT32) ((ticks % 10000000) * 100));
51/// ```
52///
53/// Example 4: Compute Timestamp from Java `System.currentTimeMillis()`.
54///
55/// ```text
56/// long millis = System.currentTimeMillis();
57///
58/// Timestamp timestamp = Timestamp.newBuilder().setSeconds(millis / 1000)
59/// .setNanos((int) ((millis % 1000) * 1000000)).build();
60/// ```
61///
62/// Example 5: Compute Timestamp from Java `Instant.now()`.
63///
64/// ```text
65/// Instant now = Instant.now();
66///
67/// Timestamp timestamp =
68/// Timestamp.newBuilder().setSeconds(now.getEpochSecond())
69/// .setNanos(now.getNano()).build();
70/// ```
71///
72/// Example 6: Compute Timestamp from current time in Python.
73///
74/// ```text
75/// timestamp = Timestamp()
76/// timestamp.GetCurrentTime()
77/// ```
78///
79/// # JSON Mapping
80///
81/// In JSON format, the Timestamp type is encoded as a string in the
82/// [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the
83/// format is "{year}-{month}-{day}T{hour}:{min}:{sec}\[.{frac_sec}\]Z"
84/// where {year} is always expressed using four digits while {month}, {day},
85/// {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
86/// seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),
87/// are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
88/// is required. A proto3 JSON serializer should always use UTC (as indicated by
89/// "Z") when printing the Timestamp type and a proto3 JSON parser should be
90/// able to accept both UTC and other timezones (as indicated by an offset).
91///
92/// For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past
93/// 01:30 UTC on January 15, 2017.
94///
95/// In JavaScript, one can convert a Date object to this format using the
96/// standard
97/// [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)
98/// method. In Python, a standard `datetime.datetime` object can be converted
99/// to this format using
100/// [`strftime`](https://docs.python.org/2/library/time.html#time.strftime) with
101/// the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one can use
102/// the Joda Time's \[`ISODateTimeFormat.dateTime()`\](
103/// <http://joda-time.sourceforge.net/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime(>)
104/// ) to obtain a formatter capable of generating timestamps in this format.
