Firestore API - Struct Timestamp (3.3.0)

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.

Implements

IEquatable Timestamp, IComparable, IComparable Timestamp

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)

Converts a DateTime to a Timestamp.

Parameter
Name	Description
`dateTime`	`DateTime` The value to convert; its kind must be Utc.

Returns
Type	Description
`Timestamp`	A Timestamp representation of `dateTime`.

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.

Remarks

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`

Overrides

ValueType.GetHashCode()

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 `DateTimeOffset`.

Remarks

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`

Overrides

ValueType.ToString()

Operators

operator ==(Timestamp, Timestamp)

public static bool operator ==(Timestamp lhs, Timestamp rhs)

Operator overload to compare two Blob values for equality.

Parameters
Name	Description
`lhs`	`Timestamp` Left value to compare
`rhs`	`Timestamp` Right value to compare

Returns
Type	Description
`bool`	true if `lhs` is equal to `rhs`; otherwise false.

operator >(Timestamp, Timestamp)

public static bool operator >(Timestamp lhs, Timestamp rhs)

Compares two timestamps.

Parameters
Name	Description
`lhs`	`Timestamp` The left timestamp to compare.
`rhs`	`Timestamp` The right timestamp to compare.

Returns
Type	Description
`bool`	true is `lhs` is strictly later than `rhs`; otherwise false.

operator >=(Timestamp, Timestamp)

public static bool operator >=(Timestamp lhs, Timestamp rhs)

Compares two timestamps.

Parameters
Name	Description
`lhs`	`Timestamp` The left timestamp to compare.
`rhs`	`Timestamp` The right timestamp to compare.

Returns
Type	Description
`bool`	true is `lhs` is later than or equal to `rhs`; otherwise false.

operator !=(Timestamp, Timestamp)

public static bool operator !=(Timestamp lhs, Timestamp rhs)

Operator overload to compare two Blob values for inequality.

Parameters
Name	Description
`lhs`	`Timestamp` Left value to compare
`rhs`	`Timestamp` Right value to compare

Returns
Type	Description
`bool`	false if `lhs` is equal to `rhs`; otherwise true.

operator <(Timestamp, Timestamp)

public static bool operator <(Timestamp lhs, Timestamp rhs)

Compares two timestamps.

Parameters
Name	Description
`lhs`	`Timestamp` The left timestamp to compare.
`rhs`	`Timestamp` The right timestamp to compare.

Returns
Type	Description
`bool`	true is `lhs` is strictly earlier than `rhs`; otherwise false.

operator <=(Timestamp, Timestamp)

public static bool operator <=(Timestamp lhs, Timestamp rhs)

Compares two timestamps.

Parameters
Name	Description
`lhs`	`Timestamp` The left timestamp to compare.
`rhs`	`Timestamp` The right timestamp to compare.

Returns
Type	Description
`bool`	true is `lhs` is earlier than or equal to `rhs`; otherwise false.
