How do I set the time?

SET UP is performed once during
installation to set the internal CLOCK, ASTRO (sunrise/sunset)
times and HOLIDAY references. After entering and okaying the
ASTRO Zone, the timer will display calculated "center of time
zone" times when prompting for sunrise and sunset entries. You
may OK these, enter actual sunrise/sunset times or enter offset
times for early or late ASTRO operation. Sunrise time must be
before noon; sunset time must be after noon. Sunset must not be
within 5 hours of sunrise. Both sunrise and sunset must be
entered, even if only one is used for switching. If neither is
required, you may skip ahead by pressing HLDY or PROG keys.
(See map pp. 24-25 for details.) Holidays are entered with 2-digit
reference numbers; a chart for recording the date(s) is located on
page 22. Leap years are preset through the year 2094

PROGRAM is used for entering or
changing the switching schedule for loads wired into the time
switch. You can program circuits separately or concurrently. Each
entry affects loads whose Enable switches are in the enable
position at the time of data entry (2 circuit models only). The
time switch is shipped in a 12-hr. AM/PM mode; you can change
to 24-hr. by removing a jumper on the circuit board (see Special
Instructions). It can store a minimum of 400 events, depending
on the data type entered.
The time switch prompts you through SET UP and PROGRAM
with LEDs that advance after each entry. There are five important
points to remember:
1) The RUN/SET switch must be in the SET position to enter,
review or change data.
2) You must press "OK" after each entry, before starting the next.
3) You must press AM or PM after entering time (unless
programming Sunrise and Sunset or in 24-hour mode).
4) When in PROGRAM you must select the loads you want to
control with the Enable switches (2 circuit models only).
5) RUN/SET switch must be returned to RUN position to enable
automatic control and to save changes to data.

These keys are used for most data entry. Note dual functions,
numeric or day specific. Using the day group keys WKDY,
WKND and ALL (for all 7 days) greatly speeds the process.
The keypad keys are only functional when the RUN/SET switch is
in the SET position. Pressing keys when in the RUN position will
cause a message to scroll, explaining the function of that key. Press
any key once to stop any of the scrolling error or help messages

You must press AM or PM after entering time data (except Sunrise
or Sunset) unless in 24-hr. mode. Programming fixed times for
ON and OFF events does not require PULSE, INTVL or ASTRO
keys. Multiple ONs or OFFs can be entered by pressing OK
without programming the alternate OFF or ON. Multiple OFF
times are frequently used to "sweep" off loads which have been
manually switched on after normal occupancy hours.
PULSE and INTVL (Interval) are length-of-time based options.
Maximum Pulse is 127 sec.; minimum is 1 sec. Maximum Interval
is 6 days, 23 hrs., 59 min.; minimum is 1 min. To program Pulses
or Intervals, press the PULSE or INTVL key after entering a Switch
On or Switch Off time; then enter the required duration and press
OK. Note after ON Pulses or Intervals have timed out the load
will be OFF, and after OFF Pulses or Intervals have timed out the
load will be ON, regardless of the load state prior to the start of
the Pulse or Interval. The INTVL and PULSE keys include a
temporary override function with a maximum length of 6 days, 23
hrs. and 59 min. for the interval or 127 seconds for the pulse. To
program an interval or pulse for override, select SET, enable the
circuit, press PROG, press INTVL
or PULSE (without selecting a
day), key in the interval or pulse

On the sunrise/sunset setting the sun is always dark as if for night. How do i get to the light cycle ?

You posted under ST01C Intermatic timer.
The Intermatic has a battery
If you have another timer, such as the Utilitec, please answer and I will help you with that problem.

Here is the ST01C manual:

If I understand correctly, you are programming the timer for the first time.
And you want to set timer for sunrise/sunset.

I have a ST01C in my hand right now
Section 6 says you can select astronomic function which is dawn-to-dusk
I notice that when you want to get to the Dusk cycle, you press ON-off button until Dawn shows ... and then press + key and Dusk shows on display

Answer back. These timer manuals are hard to figure out sometimes.

Utilitech self-adjusting wall timer 0192773. I hooked up the timer (4 wires). The automatic modes does not work and will not turn on and off the lights on set times. All it will do is turn lights on and...

I have been testing the 0192773, and other timers, for wire and program difficulties.
Good news: your timer is wired correctly. This timer will not operated lights with incorrect wiring.

programming steps are long, but same as other programmable timers.
The 0192773 is a 7-day or sunrise/sunset timer

1) Most programmable timers will not 'work as expected' if there is a conflict in programming.
They suggest you make a schedule of times before programming

2) One of the things this timer offers are individual days -or- groups of days > for example weekend only -or- weekdays only -or- all days of week -plus- individual days. For me, it was a bit confusing keeping that straight while programming

3) Each Program has ON time and OFF time
So Program1 ON has to be set same days as Program1 OFF

4) The other difficulty was how fast the display shifted back to current time when I was programming. If I looked at the instructions for a moment, my display would change before I could catch up. So it's possible that an ON or OFF time could be missed easily.

5) Finally, if you are using the timer as a sunrise/sunset, you need to enter Sunrise or Sunset with program1 ON and program1 OFF

I think the problem is in your programs:
You can use paperclip and hold in reset button for a few seconds and start over
You can press PROG button and and re-check and re-set each program.

By the way, when setting current time, I noticed the timer let you chose a year up to the year 2099. I thought that was an optimistic outlook for both operator and timer.

Programming Utilitech Item # 0192773

Go through the normal setup. Year, month, day, time, DST and the location (north, center, south).

Hit program and make sure all events are clear. Program the first (ON) event, press the TIME button and press /- (with the hour segment blinking) until you see the Sun/Moon symbol indicating the sunset time. Press PROG and program the (OFF) event. Press the /- buttons until you see the Sun/Moon symbol indicating the sunrise time.

Hitting resume clears events if you accidentally entered them.

Make sure you display shows AUTO and you're good to go.

I have a utilitech 0192773 self adjusting timer that will not program. Only works with manual on / off switch. How do you adjust to dusk to dawn

Do not go to; it's a different company. It's actually at place called TheNCC and is in tiny, tiny print at the bottom of the instructions.

Instead, go to:

You should find a PDF for the product and then zoom in to be able to read the instructions. I was not able to read instructions that came in packaging.
