GETTIM is a Fortran runtime subroutine, not a TRNSYS-specific routine. 
In order to call GETTIM in a Type you need to USE the module where it is 
declared:

! With CVF 6.6b
use dflib
...
integer(2) :: tmphour, tmpminute, tmpsecond, tmphund
...
call gettim(tmphour, tmpminute, tmpsecond, tmphund)

! With IVF 8.1
use ifport
...
integer(4) :: tmphour, tmpminute, tmpsecond, tmphund
...
call gettim(tmphour, tmpminute, tmpsecond, tmphund)

I would prefer to use the DATE_AND_TIME routine because it is an 
intrinsic routine (you do not need to explicitely use a module):

Example from the CVF help:

Consider the following example executed on 2000 March 28 at 11:04:14.5:
  INTEGER DATE_TIME (8)
  CHARACTER (LEN = 12) REAL_CLOCK (3)
  CALL DATE_AND_TIME (REAL_CLOCK (1), REAL_CLOCK (2), &
                      REAL_CLOCK (3), DATE_TIME)

This assigns the value "20000328" to REAL_CLOCK (1), the value 
"110414.500" to REAL_CLOCK (2), and the value "-0500" to REAL_CLOCK (3). 
The following values are assigned to DATE_TIME: 2000, 3, 28, -300, 11, 
4, 14, and 500.

The following shows another example:

CHARACTER(10) t
CHARACTER(5) z
CALL DATE_AND_TIME(TIME = t, ZONE = z)


Kind regards,
