Hi Guys,
I have my Pico W network date update code working consistently now. It includes a Time Zone offset and ignores day light saving.
I have found that this process can make more sense if you turn off time sync within Thonny. Details are in the main program comments.
I have left my debugging code in. Just set the debug level to zero to disable it. I usually do my debugging this way as it is sometimes useful to turn it back on down the track. There is also a debug to file option when running without a console.
I have included several methods in separate files as they will be useful to include in other programs.
I notice when I execute the program directly on the Pico as main.py, if I inspect the log file (datalog.scv) the initial date is 01/01/2021. I have not see this date mentioned in any discussion posts anywhere.
Even with the Thonny date time settings disabled I still get different result when running within Thonny.
Anyway, the code below is now working and will be useful in my project as will the reusable debugging and date formatting code.
Hope this helps someone else.
main.py
# A simple example that:
# - Connects to a WiFi Network defined by "ssid" and "password" in secrets.py
# - Sets the system time from the internet using ntp protocol.
# - Optional
# - Performs a GET request (loads a webpage)
# - Queries the current time from a server
# Thonny automatically sets the device clock every time the the program is executed.
# To avoid total confusion during testing change the following settings to false
# From the menut - Tools -> Open Thonny Data Folder
# Edit the Configuration.ini
# Change these two settings
# sync_time = True
# local_rtc = True
# Found another example here
# https://gist.github.com/aallan/581ecf4dc92cd53e3a415b7c33a1147c
# That has been modified and saved into a module ntpClient.py
# It accepts a time zone offset and saves the time to the system clock.
