dcdifftimecreate2d()

subroutine dcdifftimecreate2d	(	type(dc_difftime), intent(out)	diff,

Create DC_DIFFTIME type variable with value and unit

Create dc_date_types::DC_DIFFTIME type variable. Specify value with value argument and unit with unit string or unit symbol with unit_symbol.

Valid strings for unit (case insensitive):

Unit	String
Year	dc_date_types::UNIT_YEAR
Month	dc_date_types::UNIT_MONTH
Day	dc_date_types::UNIT_DAY
Hour	dc_date_types::UNIT_HOUR
Minute	dc_date_types::UNIT_MIN
Second	dc_date_types::UNIT_SEC
Nondimensional	dc_date_types::UNIT_NONDIM

If invalid string is given to unit, an error occurs.

Valid symbols for unit_symbol:

Unit	Symbol
Year	dc_date_types::UNIT_SYMBOL_YEAR
Month	dc_date_types::UNIT_SYMBOL_MONTH
Day	dc_date_types::UNIT_SYMBOL_DAY
Hour	dc_date_types::UNIT_SYMBOL_HOUR
Minute	dc_date_types::UNIT_SYMBOL_MIN
Second	dc_date_types::UNIT_SYMBOL_SEC
Nondimensional	dc_date_types::UNIT_SYMBOL_NONDIM

If invalid symbol is given to unit_symbol, an error occurs. If err argument is given, .true. is returned to err and the program continues.

Parameters

[out]	diff	Created DC_DIFFTIME variable
[in]	value	Value
[in]	unit	Unit string
[in]	unit_symbol	Unit symbol
[out]	err	Exception handling flag
