// Package timestamppb contains generated types for google/protobuf/timestamp.proto. // // 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
package timestamppb import ( protoreflect protoimpl reflect sync time unsafe ) // 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. type Timestamp struct { state protoimpl.MessageState `protogen:"open.v1"` // Represents seconds of UTC time since Unix epoch // 1970-01-01T00:00:00Z.
