- Learn how to use the 'ntptime' library on the to synchronize your ESP32's date and time with an NTP server! No real-time clock or other external hardware is needed.

I finally found an understandable channel .. waiting for the next video!
Do you remember wind-up clocks? Having to check the time on the clock ticking away on your bedside table every time you happened to hear the radio announce the time so you could adjust it? Of course after the apocalypse, there will be no internet so wind up clocks will be in demand again and everyone will have to re-learn how to read an analog clock. Until then I will incorporate your simple time example in most of my esp8266 or esp32 projects. Thank you!
Very informative and easy to understand.Have looked at heaps of other videos on this subject and yours was the easiest to understand,well done.
yay! Glad it helped
all your videos are really interesting and I love learning about micro python, this channels underrated for how much you can learn from it.
Glad to hear it! 😄
👏👏

Hi Bhavesh,
many thanks for this super video.
I have one problem/question:
I'm living here in germany and my problem is the switching between winter (UTC_DELAY = 1 h) and summer (UTC_DELAY = 2h) - time
Any idea how to achieve this AUTOMATICALY!
Great question! You can add some simple logic to check the date and see if it's before or after the last Sunday of the month in March/October.
Alternatively, it may be easier to just use this API to determine if daylight savings is "true" or "false" at the current time, and use that to adjust your UTC_DELAY: worldtimeapi.org/
For the 2nd option, please see my short video on how to make web requests with Micropython (the "Joke API" video)
Hope this helps! Good luck 😀
DAMN! explained a bit advance topic very easily and shortly😅
Used a ESP8266 with MU editor, it works like a charm. However, when I use a ESP32 with Thonny editor I can not get the ntptime.settime() to work, Strange. Thanks for your tutorial
I was using Micropython V1.14, had to upgrade to V1.18. Now the esp32 works also
Which NTP server will it ask? Can I set a different one? Thanks for your videos!
Hi Andreas, it asks "pool.ntp.org" as you can see in the source code, assigned to the "host" variable: (github.com/micropython/micropython-lib/blob/master/micropython/net/ntptime/ntptime.py )
If you need to set it to a different server, maybe your best bet is to just copy the simple source code above and change the "host" variable to the one you want
@@BhaveshKakwani Oh wow many thanks I didn't know where the sourcecode is.. I'll make something like a pull request to make it configurable, sometimes one must use a local one.
@@AndreasDelleske That would be great! Lemme know if you need help with it. Should just be a simple optional parameter (with default value of pool.ntp.org) to the function, I think
@@BhaveshKakwani I will: Let''s hope for the best..
I have this error
ModuleNotFoundError: No module named 'ntptime'
And I have tryed to do pip install ntptime but can't
Hi Rayos! Are you running on an ESP32? Which version of MicroPython are you using?
@@BhaveshKakwani ESP32? i don'0t know it, I run it from windows.
OH micro python is not python? :S
Yes, “Micropython” is different and it’s made specifically for electronics/hardware projects. Similar to Arduino, if you are familiar with that.
If you want to access NTP servers in normal Python, you should use the ntplib library: github.com/cf-natali/ntplib
How do I make NTP work in pi pico w?
Hi Freddie, looks like the "ntptime" library doesn't exist for pi pico W. But not to worry! You can do it semi-manually using sockets. There's a great example code here you can use: gist.github.com/aallan/581ecf4dc92cd53e3a415b7c33a1147c
how do i get the hour minute and second separately
Great question! Since the time is output as a tuple, you can treat it like any normal tuple or list in Python:
hour = actual_time[3]
minute = actual_time[4]
second = actual_time[5]
@@BhaveshKakwani if you don't mind me asking is their a way to get the time in a 12 hour format
@@ihsanshafi1047 Yes totally. Write a simple "if" condition that does this:
- If the hours is greater than 12, subtract 12 to convert into 12-hr format and add "PM" to it.
- If the hours is less than 12, just add "AM" to it
- If the hours is exactly 12, then it is 12 PM
- If the hours is exactly 0, then it is 12 AM
For example: 21 is greater than 12, so subtract 12 to get "9 PM"
Another example: 6 is less than 12, so it is "6 AM"
