Methods

GetDateTime(long)

Convert the passed in time in milliseconds to a DateTime object.

Declaration

public static DateTime GetDateTime(long timeMillis)

Parameters

Type	Name	Description
long	timeMillis	A timestamp in milliseconds since the 1/1/0001.

Returns

Type	Description
DateTime	A corresponding DateTime object for the passed in time in milliseconds.

GetLastSafeTimeMillis()

Returns the last "safe" time as computed by a previous call to the GetSafeTimeMillis method. Note: Since the underlying field is non-volatile, the returned value is only guaranteed to be no less than the last value returned by GetSafeTimeMillis() call on the same thread.

Declaration

public long GetLastSafeTimeMillis()

Returns

Type	Description
long	The last "safe" time in milliseconds.

GetSafeTimeMillis()

Returns a "safe" current time in milliseconds.

Declaration

public static long GetSafeTimeMillis()

Returns

Type	Description
long	The difference, measured in milliseconds, between the corrected current time and midnight, January 1, 0001.

Remarks

This method guarantees that the time never "goes back". More specifically, when called twice on the same thread, the second call will never return a value that is less then the value returned by the first call. If a system time correction becomes necessary, an attempt will be made to gradually compensate the returned value, so in the long run the value returned by this method is the same as the system time.

GetTimeMillisFromEpochBasedTime(long)

Convert the passed in time in milliseconds from time since the epoch (Jan 1, 1970) to time since 1/1/0001.

Declaration

public static long GetTimeMillisFromEpochBasedTime(long timeMillis)

Parameters

Type	Name	Description
long	timeMillis	A timestamp in milliseconds since the epoch (Jan 1, 1970).

Returns

Type	Description
long	The passed in time converted to milliseconds since the 1/1/0001.

GetTimeMillisSinceTheEpoch(long)

Convert the passed in time in milliseconds from time since 1/1/0001 to time since the epoch (Jan 1, 1970).

Declaration

public static long GetTimeMillisSinceTheEpoch(long timeMillis)

Parameters

Type	Name	Description
long	timeMillis	A timestamp in milliseconds since 1/1/0001.

Returns

Type	Description
long	The passed in time converted to milliseconds since the epoch (Jan 1, 1970).

IsBeforeTheEpoch(long)

Return whether the passed in time in milliseconds is before the epoch (Jan 1, 1970).

Declaration

public static bool IsBeforeTheEpoch(long timeMillis)

Parameters

Type	Name	Description
long	timeMillis	A timestamp in milliseconds since 1/1/0001.

Returns

Type	Description
bool	True if the passed in time in milliseconds is before the epoch (Jan 1, 1970).
