 **A digital clock with perpetual calendar, alarm, countdown timer/appliance timer, and day counter.** Written for the Arduino Nano at the heart of [RLB Designs'](http://rlb-designs.com/) Universal Nixie Driver Board (UNDB) v5.0, featuring a DS3231 real-time clock, and driving up to 6 digits multiplexed in pairs via two SN74141 driver chips.

-| **Time** | `12 34 56` | The time of day. You can choose 12h or 24h format in the options menu (1). When setting, it's in 24h format (so you can tell AM from PM) and the seconds will reset to :00 when you save. The clock keeps time during power outages and compensates for temperature effects.<br/><br/>If your clock is controlling an appliance (relay in switch mode), use **Adjust** here to switch it on and off manually. |

 | **Date** | `_2 _4 _0`<br/>(for&nbsp;Sun&nbsp;2/4) | You can choose the date format in the options menu (2). Setting is done in three stages: first year, then month, then date.<br/>Weekdays are: 0=Sun, 1=Mon, 2=Tue, 3=Wed, 4=Thu, 5=Fri, 6=Sat |
 | **Alarm** | `_7 00 1_` | Shows alarm time (always in 24hr format) and on/off status on 5th tube (1=on, 0=off) and by display brightness (bright=on, dim=off). Use **Adjust** to switch on/off. Hold **Select** to set time (same way as **Time**). When alarm sounds, press **Select** to snooze, or hold for 1sec (followed by a short beep) to silence the alarm for the day. Options menu lets you restrict the alarm to your workweek or weekend only. In a power outage, the alarm will remain set, but it will not sound if power is disconnected at alarm time. |
-| **Timer** | `__ __ _0` | A countdown timer, in hours, minutes, and seconds; or `0` when stopped. Can be set to the minute, up to 18 hours. Begins running as soon as you set it, and will continue to run in the background if you change to a different function. To cancel while running, hold **Select**. When timer runs out, press **Select** to silence. If power is lost, the timer will reset to `0`. Can be configured to work as an interval timer in the options menu (10), or as an appliance timer instead (see Hardware Configuration). |

 | **Day counter** | `_1 23 __` | Shows the number of days until/since a date you specify. Set the same way as **Date.** |
 | **Temperature** | `__ 38 25` | (Disabled by default.) Shows the temperature of the onboard DS3231 chip (e.g. 38.25°C – I think). May not be very useful as it tends to read higher than ambient temperature and its tolerance is low. |
 | **Tube tester** | `88 88 88` | (Disabled by default.) Cycles through all the digits on all the tubes. |
