public static final class Timestamp.Builder

implements TimestampOrBuilder

 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).
 # 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, though only UTC (as indicated by "Z") is presently supported.
 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.

```
protected GeneratedMessageV3.FieldAccessorTable internalGetFieldAccessorTable()
```
    Description copied from class: GeneratedMessageV3.Builder
    
    Get the FieldAccessorTable for this type. We can't have the message class pass this in to the constructor because of bootstrapping trouble with DescriptorProtos.

  - 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.

    clearField in interface Message.Builder
    
    Overrides:

    Overrides:
    
    addRepeatedField in class GeneratedMessageV3.Builder<Timestamp.Builder>
  - mergeFrom
```
public Timestamp.Builder mergeFrom(Message other)
```
    Description copied from interface: Message.Builder
    
    Merge other into the message being built. other must have the exact same type as this (i.e. getDescriptorForType() == other.getDescriptorForType()). Merging occurs as follows. For each field:
    * For singular primitive fields, if the field is set in other, then other's value overwrites the value in this message.
    * For singular message fields, if the field is set in other, it is merged into the corresponding sub-message of this message using the same merging rules.
    * For repeated fields, the elements in other are concatenated with the elements in this message. * For oneof groups, if the other message has one of the fields set, the group of this message is cleared and replaced by the field of the other message, so that the oneof constraint is preserved. This is equivalent to the Message::MergeFrom method in C++.
