class
Timestamp
implements
Comparable<Timestamp>
,
Serializable
Represents a timestamp with nanosecond precision. Timestamps cover the range [0001-01-01, 9999-12-31].
Timestamp
instances are immutable.
Static Fields
MAX_VALUE
public
static
final
Timestamp
MAX_VALUE
The largest legal timestamp ("9999-12-31T23:59:59Z").
MIN_VALUE
public
static
final
Timestamp
MIN_VALUE
The smallest legal timestamp ("0001-01-01T00:00:00Z").
Static Methods
fromProto(Timestamp proto)
public
static
Timestamp
fromProto
(
Timestamp
proto
)

now
()
Creates an instance with current time.
of(Timestamp timestamp)
public
static
Timestamp
of
(
Timestamp

.
ofTimeSecondsAndNanos(long seconds, int nanos)
public
static
Timestamp
ofTimeSecondsAndNanos
(
long
seconds
,
int
nanos
)
Creates an instance representing the value of seconds
and nanos
since January
1, 1970, 00:00:00 UTC.
parseTimestamp(String timestamp)
public
static
Timestamp
parseTimestamp
(
String
timestamp
)
Creates a Timestamp instance from the given string. Input string should be in the RFC 3339 format, like '2020-12-01T10:15:30.000Z' or with the timezone offset, such as '2020-12-01T10:15:30+01:00'.
