// 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 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. |
||||
// |
||||
// |
||||
