Detailed Description

Represents timestamp without time-zone information.

Constructor & Destructor Documentation

Timestamp	(	UInt32	year,
		Month	month,
		UInt32	day
	)

Initializes as date with zero time component.

Input parameters are validated, therefore constructor throws exception if input values do not fit into their valid ranges.

Timestamp	(	UInt32	year,
		Month	month,
		UInt32	day,
		UInt32	hour,
		UInt32	minute,
		UInt32	second,
		UInt32	nanosecond
	)

Explicit timestamp initialization.

Input parameters are validated, therefore constructor throws exception if input values do not fit into their valid ranges.
