Constructor & Destructor Documentation

Timestamp() [1/6]

Timestamp

(

)

Constructs an uninitialized instance.

Timestamp() [2/6]

Timestamp ( TotalSeconds seconds, Nanosecond nanosecond )

inline

Definition at line 231 of file Timestamp.h.

Timestamp() [3/6]

Timestamp ( TotalSeconds seconds, Picosecond picosecond )

inline

Initializes from seconds and picoseconds since Jan 1, 0001, 00:00:00.

Definition at line 239 of file Timestamp.h.

Timestamp() [4/6]

Timestamp	(	Year	year,
		Month::Enum	month,
		Day	day,
		Hour	hour = 0,
		Minute	minute = 0,
		Second	second = 0,
		Nanosecond	nanosecond = 0 )

Initializes date-time from all details.

Timestamp() [5/6]

Timestamp	(	Year	year,
		Month::Enum	month,
		Day	day,
		Hour	hour,
		Minute	minute,
		Second	second,
		Picosecond	picosecond )

Initializes date-time from all details.
