tem_time_subtract_time Function

private elemental function tem_time_subtract_time(left, right) result(res)

Subtract right time definition from left (provides the minus operator).

Entries set to huge (never) will be kept as this, all other entries are simply subtracted.

Arguments

Type IntentOptional Attributes Name
type(tem_time_type), intent(in) :: left

First operant in the addition of times.
type(tem_time_type), intent(in) :: right

Second operant in the addition of times.

Return Value type(tem_time_type)

Resulting sum of left and right.
