* Convert time to ascii
|
|
|
38 |
*
|
|
|
39 |
* Purpose:
|
|
|
40 |
* This routine will convert the time ( as held in tim ) into an ascii
|
|
|
41 |
* string. The address of the string is returned to the user. The
|
|
|
42 |
* string is internally static and is of a fixed format
|
|
|
43 |
*
|
|
|
44 |
* The string format is
|
|
|
45 |
*
|
|
|
46 |
* HH:MM:SS(null) - if the time is valid.
|
|
|
47 |
* ** ** **(null) - if the time is unknown
|
|
|
48 |
*

* Parameters:
|
|
|
51 |
* tim Time to convert
|
|
|
52 |
*
|
|
|
53 |
* Returns:
|
