Routine Description:

    This function converts the UTC time expressed in seconds since 1/1/70
    to an ASCII String.

Arguments:

    Time         - Pointer to the number of seconds since 1970 (UTC).

    String       - Pointer to the buffer to place the ASCII representation.

    StringLength - The length of String in bytes.

Return Value:

    None.
