class System.TimeProvider
Assembly: System.Runtime
Inheritance: object → TimeProvider
Provides an abstraction for time.
Properties
public
TimeZoneInfo
LocalTimeZone
Gets a <see cref="T:System.TimeZoneInfo" /> object that represents the local time zone according to this <see cref="T:System.TimeProvider" /> 's notion of time.
public
long
TimestampFrequency
Gets the frequency of <see cref="M:System.TimeProvider.GetTimestamp" /> of high-frequency value per second.
Methods
public
ITimer
CreateTimer(TimerCallback callback,
object state,
TimeSpan dueTime,
TimeSpan period)
callback
A delegate representing a method to be executed when the timer fires. The method specified for callback should be reentrant,
as it may be invoked simultaneously on two threads if the timer fires again before or while a previous callback is still being handled.
state
An object to be passed to the <paramref name="callback" /> . This may be null.
dueTime
The amount of time to delay before <paramref name="callback" /> is invoked. Specify <see cref="F:System.Threading.Timeout.InfiniteTimeSpan" /> to prevent the timer from starting. Specify <see cref="F:System.TimeSpan.Zero" /> to start the timer immediately.
period
The time interval between invocations of <paramref name="callback" /> . Specify <see cref="F:System.Threading.Timeout.InfiniteTimeSpan" /> to disable periodic signaling.
Returns The newly created <see cref="T:System.Threading.ITimer" /> instance.
Creates a new <see cref="T:System.Threading.ITimer" /> instance, using <see cref="T:System.TimeSpan" /> values to measure time intervals.
public
TimeSpan
GetElapsedTime(long startingTimestamp)
startingTimestamp
The timestamp marking the beginning of the time period.
Returns A <see cref="T:System.TimeSpan" /> for the elapsed time between the starting timestamp and the time of this call.
Gets the elapsed time since the <paramref name="startingTimestamp" /> value retrieved using <see cref="M:System.TimeProvider.GetTimestamp" /> .
public
TimeSpan
GetElapsedTime(long startingTimestamp,
long endingTimestamp)
startingTimestamp
The timestamp marking the beginning of the time period.
endingTimestamp
The timestamp marking the end of the time period.
Returns A <see cref="T:System.TimeSpan" /> for the elapsed time between the starting and ending timestamps.
Gets the elapsed time between two timestamps retrieved using <see cref="M:System.TimeProvider.GetTimestamp" /> .
Gets a <see cref="T:System.DateTimeOffset" /> value that is set to the current date and time according to this <see cref="T:System.TimeProvider" /> 's
notion of time based on <see cref="M:System.TimeProvider.GetUtcNow" /> , with the offset set to the <see cref="P:System.TimeProvider.LocalTimeZone" /> 's offset from Coordinated Universal Time (UTC).
public
long
GetTimestamp() Returns A long integer representing the high-frequency counter value of the underlying timer mechanism.
Gets the current high-frequency value designed to measure small time intervals with high accuracy in the timer mechanism.
Gets a <see cref="T:System.DateTimeOffset" /> value whose date and time are set to the current
Coordinated Universal Time (UTC) date and time and whose offset is Zero,
all according to this <see cref="T:System.TimeProvider" /> 's notion of time.
public
bool
Equals(object obj)
Inherited from object
obj
The object to compare with the current object.
Returns <see langword="true" /> if the specified object is equal to the current object; otherwise, <see langword="false" /> .
Determines whether the specified object is equal to the current object.
protected
void
Finalize()
Inherited from object
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
public
int
GetHashCode()
Inherited from object
Returns A hash code for the current object.
Serves as the default hash function.
public
Type
GetType()
Inherited from object
Returns The exact runtime type of the current instance.
Gets the <see cref="T:System.Type" /> of the current instance.
protected
object
MemberwiseClone()
Inherited from object
Returns A shallow copy of the current <see cref="T:System.Object" /> .
Creates a shallow copy of the current <see cref="T:System.Object" /> .
public
string
ToString()
Inherited from object
Returns A string that represents the current object.
Returns a string that represents the current object.
