public struct Timestamp : IEquatable<Timestamp>, IComparable, IComparable<Timestamp>
Reference documentation and code samples for the Firestore API struct Timestamp.
A nanosecond-precision immutable timestamp. When this is stored as part of a document in Firestore, it is truncated to the microsecond, towards the start of time.

Methods
CompareTo(Timestamp)
public int CompareTo(Timestamp other)
Parameter | |
---|---|
Name | Description |
other | Timestamp |
Returns | |
---|---|
Type | Description |
int |
CompareTo(object)
public int CompareTo(object obj)
Parameter | |
---|---|
Name | Description |
obj | object |
Returns | |
---|---|
Type | Description |
int |
FromDateTime(DateTime)
public static Timestamp FromDateTime(DateTime dateTime)
Parameter | |
---|---|
Name | Description |
dateTime | DateTime The value to convert; its kind must be Utc. |
Returns | |
---|---|
Type | Description |
Timestamp | A Timestamp representation of |
FromDateTimeOffset(DateTimeOffset)
public static Timestamp FromDateTimeOffset(DateTimeOffset dateTimeOffset)
Converts the given DateTimeOffset to a Timestamp
Parameter | |
---|---|
Name | Description |
dateTimeOffset | DateTimeOffset The date and time (with UTC offset) to convert to a timestamp. |
Returns | |
---|---|
Type | Description |
Timestamp | The converted timestamp. |
The offset is taken into consideration when converting the value (so the same instant in time
is represented) but is not a separate part of the resulting value. In other words, there is no
roundtrip operation to retrieve the original DateTimeOffset
.
FromProto(Timestamp)
public static Timestamp FromProto(Timestamp proto)
Creates an instance from a Protobuf Timestamp representation. Later modifications to the Protobuf representation will not affect the returned oject.
Parameter | |
---|---|
Name | Description |
proto | Timestamp A Protobuf timestamp representation. Must not be null. |
Returns | |
---|---|
Type | Description |
Timestamp | An immutable timestamp. |
GetCurrentTimestamp()
public static Timestamp GetCurrentTimestamp()
Returns the current timestamp according to the system clock. The system time zone is irrelevant, as a timestamp represents an instant in time.
Returns | |
---|---|
Type | Description |
Timestamp | The current timestamp according to the system clock. |
GetHashCode()
public override int GetHashCode()
Returns | |
---|---|
Type | Description |
int |
ToDateTime()
public DateTime ToDateTime()
Converts this timestamp to a DateTime with a kind of Utc. This can lose information as DateTime has a precision of a tick (100 nanoseconds). If the timestamp is not a precise number of ticks, it will be truncated towards the start of time.
Returns | |
---|---|
Type | Description |
DateTime | A DateTime representation of this timestamp. |
ToDateTimeOffset()
public DateTimeOffset ToDateTimeOffset()
Converts this timestamp into a DateTimeOffset.
Returns | |
---|---|
Type | Description |
DateTimeOffset | This timestamp as a |
The resulting DateTimeOffset
will always have an Offset
of zero.
If the timestamp is not a precise number of ticks, it will be truncated towards the start
of time.
DateTimeOffset value precisely on a second.
ToProto()
public Timestamp ToProto()
Creates a Protobuf Timestamp representation of this timestamp. Modifications to the returned message will not be reflected in this object.
Returns | |
---|---|
Type | Description |
Timestamp | A Protobuf timestamp representation. |
ToString()
public override string ToString()
Returns | |
---|---|
Type | Description |
string |
