Only the two least significant digits of the year can be changed. The most significant digits are
always 20. Thus the date can only be changed within the range 2000 to 2099 .

Datetime.nug takes over most of the IR handset keys. When the Nuggle program is run the tubes
will display the current UTC day, month and year from the RTC. The bling around the leftmost
tube, tens of years, will light showing that tube is selected and its value can be changed. The IR
handset keys are used as follows:
• '0' .. '9' key value is applied to the selected tube. The selected tube moves one to the right. The
units seconds tube rolls over to the tens of years tubes. Using these numerical keys you can
dial in a new UTC date.
• '|<<' or Prev key will move the selected tube one position to the left. The leftmost tube rolls
under to the rightmost tube.
• '>>|” or Next key will move the selected tube one position to the right. The rightmost tube rolls
over to the leftmost tube.
• 'EQ' key accepts the UTC date as shown and writes it to the date to the RTC that will
immediately start using it. The clock will then change to show the face that was shown before
this face was selected.
• '>||' or Play key acts as a cancel or escape key, the date shown is abandoned and the clock will
then change to show the face that was shown before this face was selected.
If an illegal entry is tried, for example pressing '4' when the tens of months tube is selected, then
a warning chime will sound and the value shown on the tube will not change.
All keys not listed here will retain their default function, for example, pressing the '+' key will still
increase the chime volume. Additionally, moving the rotary encoder will change the face selected
and so effectively cancel the set date function.
Face number 962
Nuggle file syncrtc.nug
Description
Force the RTC to sync with the
GPS or WiFi (which ever
installed). The clock will revert
to the predecessor face.
Colons Not used
Bling
The tube bling LEDs will flash
green briefly on a successful
synchronisation.
Chimes None
Outside that range a constant within the C firmware must be changed and the SAM burned. In practice, a date range up to the year 2099

seems adequate…;-)
