Adjusting Clocks for Daylight Saving Time: Ideas & Troubleshooting

Daylight saving time (DST) adjustments had been formally established in a lot of the United States nearly 60 years in the past, however the biannual adjustments proceed to be a trouble for upkeep groups, facility managers, IT workers and anybody else in command of preserving a constructing working easily.

Listed below are some suggestions for getting ready your clocks for DST and troubleshooting if issues don’t go as deliberate.

Make sure that your synchronized clocks are prepared.

Adjusting for daylight saving time is made infinitely simpler when you’ve got a synchronized clock system that performs DST updates mechanically. Somewhat than sending workers round to manually change each clock twice a 12 months, upkeep employees can stay targeted on the opposite crucial duties that hold your facility working easily.

American Time’s clocks and clock programs get rid of the necessity for guide DST changes. Moreover, a lot of our programs, such because the SiteSync IQ® clock system, IP community clocks, and the EverAlert® communication system can leverage synchronized time to handle different programs in your constructing, resembling scheduled bells or lighting.

With automated updates to your clocks, you do not have to fret whether or not conferences or courses are beginning on time, or that bells and tones are sounding after they’re alleged to. As an alternative, you may attend to the numerous different objects in your to-do listing.

Like every other system, it is a good suggestion to carry out occasional checks in your synchronized time system to make sure it is working usually, particularly forward of a DST change. American Time’s clock programs make this simple to confirm.


Test the ability supply
To make certain a wired system clock is syncing appropriately and prepared for the time change, unplug it and wait till the time is completely different than the grasp earlier than plugging it again in. This might take as much as an hour relying on the kind of clock and whether it is geared up with a capacitor (be happy to contact us in case you’re unsure). It ought to re-sync because it receives the time sign, a course of that would take as much as 24 hours, relying on the kind of clock.

For wi-fi, power-over-Ethernet (PoE), and Wi-Fi clocks, take away the ability or battery from the receiver and watch for the clock to come back to an entire cease earlier than reconnecting energy to the clock. The clock ought to re-sync mechanically inside 24 hours. For wi-fi clocks, this may be expedited by taking the grasp out of quiet mode in case your unit is supplied previous to energy biking the clock.

Don’t neglect to examine your battery life, as nicely. If it’s supplying 1.5 volts or extra, it ought to be good to go and the clock ought to mechanically alter. For PoE and Wi-Fi programs, this may be completed from the consolation of your desk (or every other place with web entry) utilizing the inCloud Administration Portal.

Examine the Grasp Controller
Attending to particular person clocks will not do you any good if the grasp controller is not working correctly, so examine the time on the grasp controller. Make sure that it shows the right time, time zone and DST setting.

If that each one goes easily, you must don’t have anything to fret about. If it did not, examine your connections and grasp readout screens together with energy cables, antennas (the place relevant), and plugs, and see our troubleshooting suggestions beneath. Guarantee all connections are safe. If the controller makes use of Ethernet, be certain that the community settings for the grasp clock have not modified.


  • For a Wi-Fi community, be sure you’ve bought the correct settings for SSID (community identify), password and legitimate time server deal with(es).

  • If you happen to’re working with a PoE system, check out your community time servers, and the cables working to the clocks.


Troubleshooting clocks that aren’t ready

If you do not get an opportunity to examine your system earlier than the time change happens and you end up with clocks that have not up to date, it is usually a easy repair to get every little thing again up and working.

Within the occasion all your system clocks have not up to date, the difficulty is probably going associated to both the grasp controller or the settings in your community.  If particular person clocks have failed, listed below are some troubleshooting suggestions:

Take away the clock from the ability supply
That is the traditional “unplug it and plug it again in” method. Nonetheless, it’s necessary to do that to make sure that clocks are syncing appropriately and prepared for the time change. Unplug it and wait an hour earlier than plugging it again in. It ought to re-sync because it receives the time sign. This course of may take as much as 24 hours, relying on the kind of clock.

For a wi-fi clock, take away the ability and watch for the clock to come back to an entire cease earlier than making use of energy. The clock ought to re-sync mechanically inside 24 hours.

Battery life
In case you are working battery-powered clocks, examine the battery life. If the voltage is healthier than 1.5 volts, the batteries ought to survive the time change with out issues. In the event that they should be modified, be sure you change all of the batteries with new, unused batteries.

 SiteSync and Wi-Fi battery clocks ought to solely use lithium AA batteries. 

If you happen to even have non-corrective AllSet or Atomic clocks in your facility, these ought to solely use alkaline batteries.

Test connections
Make sure that the connections are strong and tight. This consists of energy cables, antennas and plugs.
Test system settings
Make sure that your system settings are dialed in. That features checking that your system controller shows the right time, time zone and DST setting.

Test community settings
You must also examine the clock’s community settings. This is find out how to examine these settings for numerous clock sorts:

  • Wi-Fi clocks – Test your community settings together with SSID, passphrase and time server.

  • PoE clocks – Test your community time servers and the cables working out of your community to the clock.

  • SiteSync IQ Wi-fi clocks: Test the ability on the system controller.

Nonetheless altering clocks by hand? Calculate your misplaced time.

If you happen to handle a big constructing or campus, you might have tons of of clocks that assist hold everybody in sync as they adhere to a good schedule. That schedule is probably going so refined that if these clocks are off by only a minute or two, the extremely calibrated schedule is not environment friendly.

But when your clocks don’t mechanically alter for DST, you’re spending a variety of time adjusting for that change and coping with work orders and complaints that the clocks are unsuitable. For example that job averages out to 5 minutes for every clock. When you have 100 clocks to regulate, that provides as much as greater than a full 8-hour work day. That is two treasured work days annually which might be devoted to the thankless job of constructing certain your clocks alter for Daylight Saving Time. Right here’s the equation:

5 minutes x 100 clocks x 2 DST occasions = 1000 minutes per 12 months

1000 minutes ÷ 60 = 16 hours

If you wish to calculate how a lot time your facility can save, plug in your info within the equation beneath. Bear in mind the various factors that may have an effect on the velocity of correcting the clock such because the expertise of the individual accountable for adjusting them, the time it takes to stroll to every room, if the clock is situated someplace that’s solely accessible by ladder, and the provision of the room. Additionally, DST happens twice a 12 months so be certain that to multiply your outcomes by 2.

[average amount of time to change one clock] x [number of clocks] x 2 DST occasions = [minutes per year it takes to adjust the clocks]

If you happen to’re nonetheless adjusting clocks by hand, it’s time to improve. We have now clock applied sciences to suit any constructing or funds, from a full wi-fi system, to increasing an present wired system, to quick-and-easy synchronization out of your present Wi-Fi community!
