Intel® Fortran Compiler 17.0 Developer Guide and Reference
Intrinsic Subroutine (Generic): Returns the current time as set within the system. TIME can be used as an intrinsic subroutine or as a portability routine. It is an intrinsic procedure unless you specify USE IFPORT. Intrinsic subroutines cannot be passed as actual arguments.
CALL TIME (buf)
buf |
(Output) Is a variable, array, or array element of any data type, or a character substring. It must contain at least eight bytes of storage. |
The date is returned as a 8-byte ASCII character string taking the form hh:mm:ss, where:
hh |
is the 2-digit hour |
mm |
is the 2-digit minute |
ss |
is the 2-digit second |
If buf is of numeric type and smaller than 8 bytes, data corruption can occur.
If buf is of character type, its associated length is passed to the subroutine. If buf is smaller than 8 bytes, the subroutine truncates the date to fit in the specified length. If an array of type character is passed, the subroutine stores the date in the first array element, using the element length, not the length of the entire array.
CHARACTER*1 HOUR(8)
...
CALL TIME (HOUR)The length of the first array element in CHARACTER array HOUR is passed to the TIME subroutine. The subroutine then truncates the time to fit into the 1-character element, producing an incorrect result.
