    is this a computer posted to computers help?
    it is not.
    so this your first time using this timer?
    or used it for years and was ok until today?
    it has batteries are they fresh?
    used in what country
    the timer is !"spec"
    "AC Line Synchronous or DC Quartz Time Base "
    so change to AC sync, if in USA.
    ours is averaged, the AC line over long time periods, others countries NOT.

    you told gain, but did not state how much.
    10seconds a day 10minutes per day.
    all non internet or radio 10mhz devices
    gain or lose time, all do. lacking the nuclear sync, (2 ways)
    same for GPS, same way.

    Simplex clocks systems
    we had many long ago. 1990 to 2010
    and we upgraded ours to use www sync
    by adding that hardware box to it.
    we also had the options of internet sync.

    long ago wwv USA radio station upgrade to 10x more power. (and wwvh Hawaii)
    and the time sync from WWW 10mhz radio , now worked in all conditions night ,day or horrible weather. 10KILO WATTS POWER.
    the internet way works good too if never goes down that is, and can. (no country told or state in usa, or islands, etc. Guam? )

    their web site , ask them for time sync upgrades , we ran WWV with zero problems for over a decade)

    owned now by Johnson controls.

    this timer is long in tooth, I found no manual.
    the manual will tell you how to switch from
    crystal time base timer to 60HZ AC line syc.
    for better you need
    to buy. (upgrades)
    wwv 10mhz, sync receiver, or web sync box options. for sure.
    was the expert then now , just drip under pressure,
    we had 100 wired clocks, and I invented a fix for those when lost time. on all. and not equal. (and for daylight savings time horrors)

    good luck that is my experience,.

    one site poster said the company almost made 100 years old. but was shy of that.
    used for school bells K to 12.lots
    or for clocks or both.
    for decades even in 1940s.(older models)

    if in USA turn on 60hz time sync.
    per the manual
    then the time will not vary on a weekly bases.
    power plants in USA vary 60hz to do just that. on average it does not vary.
    first get time correct, say using cell phone time. as master.
    then turn on 60hz sync
    now it keeps time using only AC line sync.
    the secret is , must be correct time to start.

    all clocks on earth not time sync'd to
    USA atomic clocks, gain or lose time.
    for sure cheap and old crystal based only.
    all like that drift fast, say second per day.
    your PC is sync'd the same why like this.
    called now NTP , mine is set to this. (NBS/NIST,national time standards)
    I can also time sync via wwv radio links.

    time to leave 1990 tech and move up or upgrade the 6100.

I have a simplex 6100 program timer I am trying to figure out how to set the bell schedule. I have put the bells schedule in but the bells are not ringing.

Re-check the program to verify that the bell circuits are scheduled to turn on, and that the duration is correct. I assume you have the manual since you have programmed the bell schedule. If not, it can be found here:

We have no power to our timer. I have tried the breaker with no avail. Could they have disconnected when they changed our phone system?

You will need to verify that 120V power is at the panel. If so, the problem is with the control unit power supply. If not, then something has been reconfigured in the electrical circuit.

Dell vostro laptop clock gains time

Try a system restore before this became a issue, if no! run a deep or full scan with your antivirus program, if still no change, go online to Dell and contact customer support and the technical department to see if there is a design flaw, or better still a solution to the problem.

Xerox Phaser 6100 BD

It should be on the start up or configuration page.
I know there is no info in any documentation that tells you where to gain that info.
I can't remember exactly what page it is on, but the count is on one of those 2 pages.
