How to Read the ESP32 Internal Real-Time Clock (RTC) - Arduino Tutorial

[@feynthefallen]

Oh wow, you are showing us how to open a pre-made example! Such savvy! Very programmer! Much knowledgeable!

[@OsoAstuto]

You're free to do one better.

Thanks for the video, I've heard that before but don't know how to set😅

[@herrkronen9694]

Thanks for the video ! , how can i set the offset for GMT -4:30 ?

[@adtechknow2761]

Thanks!. Try setting offset -16200..

[@herrkronen9694]

@@adtechknow2761 how You calculate that númber ? Is there some explanation in library source code ?

[@herrkronen9694]

Yes indeed, there is a line inside library that says the parameter "OFFSET" should be in SECONDS. I just checked and if you need -4:30GMT is -16200seconds. I haven't proved yet, but thanks a lot @@adtechknow2761

(4*60*60)+(30*60)=16200

[@patilabhijeetj]

Basically it's difference between total number of seconds from GMT. So in your case convert 4 hours into seconds i.e. 4x60x60 Then for 30 minutes it will be 30x60 Sum these two results to get 16200. Hope this helps

Great, easy to use library. This was a real time saver, thanks!!

[@adtechknow2761]

Glad it helped!

[@jasonmare33]

can you use this internal clock as a on/ off timer

[@muhammadadnanahmed8324]

Dear, when esp32 turn OFF and then turn ON after 30mins time will change, if so what to do for this

[@С-8КОМ]

you will need to update it using an external source like a small RTC clock with redundancy battery or through the internet. So if turns off the time is tracking
