setTime() does not set system time

Describe the bug

According to the docs, setTime() will "// set the system time to UTC". However time() still reports uptime seconds.

Steps to Reproduce

In DS323x_Generic/examples/Time/ESP/RTC_ESP/RTC_ESP.ino , call time() function.

Expected behavior

time() should contain the same value as rtc.now()

Actual behavior

time() is unaffected.

Information

Please ensure to specify the following:

  • Arduino IDE version 1.8.19
  • ESP8266 Core Version ESP8266 core v3.0.0
  • Contextual information - set system time from RTC
  • Call time() function from RTC_ESP example

The setTime() function is one of the TimeLib library and it certainly can't know about every board to set the system time. You can post an issue there to ask for help.

Also check the similar issue in ESP8266 Forum TIMELIB : HOW TO SET TIME(NULLPTR) ?

You can also adapt this NTP-TZ-DST example to use.

It's your responsibility to set the system time yourself, if you'd like to use, when you already have the accurate time from RTC.

As this issue has nothing to do with this library, I'm closing it now.

Good Luck,

Hi @rnsi

I already write a new example RTC_ESP_Complex to serve your purpose.

Best Regards,

Releases v1.2.3

  1. Optimize code by using passing by reference instead of by value
  2. Add ESP_Complex examples to update system time from RTC time. Check setTime() does not set system time #1
  3. Update Packages' Patches
