### Methods

- Fl_Clock
- ~Fl_Clock
- hour
- minute
- second
- value

#### Fl_Clock::Fl_Clock(int x, int y, int w, int h, const char *label = 0)

Creates a new `Fl_Clock` widget using the given position, size, and label string. The default boxtype is `FL_NO_BOX`.

#### virtual Fl_Clock::~Fl_Clock()

The destructor also deletes all the children. This allows a whole tree to be deleted at once, without having to keep a pointer to all the children in the user code. A kludge has been done so the `Fl_Clock` and all of it's children can be automatic (local) variables, but you must declare the `Fl_Clock`first, so that it is destroyed last.

#### int Fl_Clock::hour() const

Returns the current hour (0 to 23).

#### int Fl_Clock::minute() const

Returns the current minute (0 to 59).

#### int Fl_Clock::second() const

Returns the current second (0 to 60, 60 = leap second).

#### void Fl_Clock::value(ulong v)
void Fl_Clock::value(int h, int m, int s)
ulong Fl_Clock::value(void)

The first two forms of `value` set the displayed time to the given UNIX time value or specific hours, minutes, and seconds.

The third form of `value` returns the displayed time in seconds since the UNIX epoch (January 1, 1970).
