// 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.////message Timestamp { // Represents seconds of UTC time since Unix epoch // 1970-01-01T00:00:00Z. Must be from 0001-01-01T00:00:00Z to // 9999-12-31T23:59:59Z inclusive. int64 seconds = 1; // Non-negative fractions of a second at nanosecond resolution. Negative // second values with fractions must still have non-negative nanos values // that count forward in time. Must be from 0 to 999,999,999 // inclusive. int32 nanos = 2;}
