# hsec¶

## Purpose¶

Returns the number of hundredths of a second since midnight.

## Examples¶

```
// Define random x matrix
x = rndu(1000, 1000);
// Starting time
tStart = hsec;
// Multiply x*x
y = x*x;
// Calculate time elapsed
tTotal = hsec-tStart;
```

In this example, `hsec()`

is used to time a 1000x1000 multiplication in GAUSS. A 1000x1000 matrix,
*x*, is created, and the current time, in hundredths of a
second since midnight, is stored in the variable *tStart*.
Then the multiplication is carried out. Finally, *tStart*
is subtracted from `hsec()`

to give the time difference
which is assigned to *tTotal*.
