public final class Timestamp
extends GeneratedMessage
implements TimestampOrBuilder

Protobuf type google.protobuf.Timestamp

 A Timestamp represents a point in time independent of any time zone
 or calendar, represented as seconds and fractions of seconds at
 nanosecond resolution in UTC Epoch time. It is encoded using the
 Proleptic Gregorian Calendar which extends the Gregorian calendar
 backwards to year one. It is encoded assuming all minutes are 60
 seconds long, i.e. leap seconds are "smeared" so that no leap second
 table is needed for interpretation. 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 date strings.
 See [https://www.ietf.org/rfc/rfc3339.txt](https://www.ietf.org/rfc/rfc3339.txt).
 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.
     now = time.time()
     seconds = int(now)
     nanos = int((now - seconds) * 10**9)
     timestamp = Timestamp(seconds=seconds, nanos=nanos)

  - getDefaultInstanceForType
```
public Timestamp getDefaultInstanceForType()
```
    Description copied from interface: MessageLiteOrBuilder
    
    Get an instance of the type with no fields set. Because no fields are set, all getters for singular fields will return default values and repeated fields will appear empty. This may or may not be a singleton. This differs from the getDefaultInstance() method of generated message classes in that this method is an abstract method of the MessageLite interface whereas getDefaultInstance() is a static method of a specific class. They return the same thing.
