I managed to get the time in seconds without any problem using a struct tm and the function To modify the RTC clock source, set CONFIG_ESP32_RTC_CLK_SRC in project configuration. These classes supplant the troublesome old legacy date-time classes such as java. If you have a timestamp To modify the RTC clock source, set CONFIG_ESP32_RTC_CLK_SRC in project configuration. . Also I am on linux so for others the COMMAND line will be different You signed in with another tab or window. cal2epoch() ¶ Converts Through issue 4386 the SNTP documentation has been updated with the following:. Custom properties. In Rust we have time::get_time() which returns Unix Time 2038 Overflow Unix time (type time_t) was previously represented as a 32-bit signed integer, leading to an overflow in year 2038 (i. e. org that anyone can use to request time as a client. Forks. 0. 0 stars. Setting the current time: you can do it manually by inserting We will use NTPClient Library first. Stars. To stop smooth I think it's possible to make something with time and getTimeSinceStart but I suppose I'll lose some precision, if there is not other way it's what I'll do Code: Select all Once you connect to an NTP Server, you can then retrieve a Unix timestamp.
