Real Time Clock adjuster - offers easy menued time and date entry.
I'm using a DS3231, but it should work for other I2C RTCs
This is something I've been wanting to do for a while to give independence against inevitable internet melt-downs, and for stand-alone portable and vehicle type projects.
Unfortunately it is now big enough to be affected by the Esp-Basic quantum weirdness complexity bug, so perhaps just use it as a demonstrator for cropping out your own minimal functionality - things like month names and day names and colours and styles are nice but non-essential, so can be pruned to give Esp-Basic a bit more wiggle room for avoiding its bug problems.
Like schrodinger's cat there's no way of knowing the outcome without trying.
If you've done 2 successful consecutive clean SAVES since the last device reboot then the probability is that the program will RUN ok.
If it doesn't, don't be tempted into chasing ghosts if the seconds don't update (note: in red edit mode the details are frozen for editing anyway), or the screen only partially displays, simply browser BACK then re-RUN and it may well then work ok... there seems no rhyme or reason to the quantum weirdness. I've found that the best chances of keeping the bug at bay is to reboot a device with 1Mb build (even if actually a 4Mb device), paste in a clean script, do a SAVE, then immediately do another SAVE, then RUN.
A possibility in the future might be for a main application script to load a dedicated RTCadjust script for adjusting the date and time parameters, which then reloads the original application script again afterwards. Both scripts could do a memclear for max resources, the application script could save and re-load any important vars from flash and/or RTC eeprom if wished.
