Re: timezone support in MicroPython ?

I'm afraid the timezones data required for such support would be about two orders of magnitude larger than the memory available on the microcontrollers supported by MicroPython. It would be enough to specify GMT (+1 for me: Rome) and legal/solar time in ntptime library. Obviously you need to know w...

timezone support in MicroPython ?

Hi,
I need to store exact time and date for my city.
So, I inserted in boot.py the following code:

Code: Select all

from ntptime import settime
settime()
so, I can read time by:

Code: Select all

import utime
utime.localtime()

Isn't there a timezone support and legal/solar time support ?
How I to do ?
