### 9.259 `TIME8` — Time function (64-bit)

Description:

  Returns the current time encoded as an integer (in the manner of the function `time(3)` in the C standard library). This value is suitable for passing to `CTIME`, `GMTIME`, and `LTIME`.

  Warning: this intrinsic does not increase the range of the timing values over that returned by `time(3)`. On a system with a 32-bit `time(3)`, `TIME8` will return a 32-bit value, even though it is converted to a 64-bit `INTEGER(8)` value. That means overflows of the 32-bit value can still occur. Therefore, the values returned by this intrinsic might be or become negative or numerically less than previous values during a single run of the compiled program.

Standard:

  GNU extension

Class:

  Function

Syntax:

  `RESULT = TIME8()`

Return value:

  The return value is a scalar of type `INTEGER(8)`.
