subroutine qtdt_s_int4arraytodate	(	type (qtdt_t_date), intent(out)	tDate,
		integer (qtdt_k_int4), dimension(3), intent(in)	iaDate
	)

qtDT_S_IntegerArrayToDate

Converts a date specification in an array into a date type.

Usage:

CALL qtDT_F_IntegerArrayToDate( tDate, iaDate )   !  tDate = iaDate(:)

Parameters

tDate	: the date type (result of conversion)
iaDate	: integer array containing a date specification (/day,month,year/) to convert

Converts a date specification in an array (/day, month, year/) into a date type.
This procedure is used to overload the assignment operator (=) to allow for assignments like

 TYPE (qtDT_T_Date) :: tDate
 INTEGER :: day = 3, month = 8, year = 1998
 INTEGER :: iaDate = (/1,4,2012/)
 tDate = (/day, month, year/)
 tDate = iaDate
 

subroutine qtdt_s_int2arraytodate	(	type (qtdt_t_date), intent(out)	tDate,
		integer (qtdt_k_int2), dimension(3), intent(in)	iaDate
	)

subroutine qtdt_s_datetoint4array	(	integer (qtdt_k_int4), dimension(3), intent(out)	iaDate,
		type (qtdt_t_date), intent(in)	tDate
	)

qtDT_S_DateToIntegerArray

Converts a date specification in an array into a date type.

Usage:

CALL qtDT_S_DateToIntegerArray( iaDate, tDate )   ! iaDate(:) = tDate

Parameters

iaDate	: integer array; result of conversion: (/day,month,year/)
tDate	: the date type value containing a date specification to be converted

Converts a date type value into an array (/day, month, year/).
This procedure is used to overload the assignment operator (=) to allow for assignments like

 TYPE (qtDT_T_Date) :: tDate = 
 INTEGER :: iaDate
 tDate = qtDT_T_Date(28,4,2014)
 iaDate(:) = tDate
 

subroutine qtdt_s_datetoint2array	(	integer (qtdt_k_int2), dimension(3), intent(out)	iaDate,
		type (qtdt_t_date), intent(in)	tDate
	)

subroutine qtdt_s_timetodaytime	(	type (qtdt_t_daytime), intent(out)	tDayTime,
		type (qtdt_t_time), intent(in)	tTime
	)

qtDT_S_TimeToDayTime

Converts a time type into a daytime type.

Usage:

CALL qtDT_S_TimeToDayTime( tDayTime, tTime )

Parameters

tDayTime	: daytime type value
tTime	: time type value

Converts a time type value into a daytime type value.
This procedure is used to overload the assignment operator (=) allowing for statements like

 TYPE (qtDT_T_DayTime) :: tDayTime
 TYPE (qtDT_T_Time) :: tTime = qtDT_T_Time(123, 40, 10, 312)
 tDayTime = tTime  ! giving: tDayTime = qtDT_T_DayTime(5, 3, 40, 10, 312)
 

subroutine qtdt_s_daytimetotime	(	type (qtdt_t_time), intent(out)	tTime,
		type (qtdt_t_daytime), intent(in)	tDayTime
	)

qtDT_S_DayTimeToTime

Converts a daytime type into a time type.

Usage:

CALL qtDT_S_DayTimeToTime( tTime, tDayTime )

Parameters

tTime	: time type value
tDayTime	: daytime type value

Converts a daytime type value into a time type value.
Since the time type value is restricted to a maximum value of 596:31:23:647 (see qtDT_F_TimeToIntegerMS for explanation), tDayTime days should not exceed the value of 24 days, otherwise the function will return faulty values.
This procedure is used to overload the assignment operator (=) allowing for statements like

 TYPE (qtDT_T_DayTime) :: tDayTime = qtDT_T_DayTime(5, 3, 40, 10, 312)
 TYPE (qtDT_T_Time) :: tTime
 tTime = tDayTime  ! giving: tTime = qtDT_T_Time(123, 40, 10, 312)
