I have an ESP32 board, with Micropython installed properly, and connecting to local the internet.

Since it have to do a scheduled jobs- its clock need to be synced. From this post on the Micropython forum:. From this discussionyou need to make sure you have an active internet connection before trying to set the time, and you should expect to get occasional timeout errors and handle these appropriately.

There are a few categories of such modules:.

On some ports you are able to discover the available, built-in libraries that can be imported by entering the following at the REPL:. Beyond the built-in libraries described in this documentation, many more modules from the Python standard library, as well as further MicroPython extensions to it, can be found in micropython-lib. They provide the core functionality of that module and are intended to be a drop-in replacement for the standard Python library. This is to signify that such a module is micro-library, i.

By naming them differently, a user has a choice to write a Python-level module to extend functionality for better compatibility with CPython indeed, this is what done by the micropython-lib project mentioned above. On some embedded platforms, where it may be cumbersome to add Python-level wrapper modules to achieve naming compatibility with CPython, micro-modules are available both by their u-name, and also by their non-u-name.

The non-u-name can be overridden by a file of that name in your library path sys. For example, import json will first search for a file json.

If nothing is found, it will fallback to loading the built-in ujson module. Functionality specific to the MicroPython implementation is available in the following libraries. Where this occurs, the entry in the port specific library exposes hardware functionality unique to that platform. To write portable code use functions and classes from the machine module. To access platform-specific hardware use the appropriate library, e.

I am currently can't figure out how to use that undocumented example to use it to run tasks on specific timings. Polling the getLocalTime routine can't be the right way to use it, is it? You are saying ntp sync is built into ESP itself? If you drill down into esp-hal you can merge more features Let us know how it works. I think I saw some information pertaining to deep sleep that only certain level of interrupt can wake the device up.

Or maybe it is some kind of external event signal - hopefully can be periodic.

I think there is an issue with RTC in ntptime. I tried it by removing the RTC functions and it worked fine. I get no response maybe because settime function isn't returning any value according to ntptime. When i downloaded the ntptime. I also tried with the RTC part and just added return to the settime function, it still gave me the same to errors. Here is the log with RTC part removed and return value added:.

For more information, refer to the original CPython documentation: time. The utime module provides functions for getting the current time and date, measuring time intervals, and for delays. However, embedded ports use epoch of UTC.

On baremetal ports however system time depends on machine. RTC object. The current calendar time may be set using machine. Convert a time expressed in seconds since the Epoch see above into an 8-tuple which contains: year, month, mday, hour, minute, second, weekday, yearday If secs is not provided or None, then the current time from the RTC is used.

This is inverse function of localtime. It returns an integer which is the number of seconds since Jan 1, Sleep for the given number of seconds. Some boards may accept seconds as a floating-point number to sleep for a fractional number of seconds.

Returns an increasing millisecond counter with an arbitrary reference point, that wraps around after some value. Thus, these functions will return a value in range [ Note that only non-negative values are used.

For the most part, you should treat values returned by these functions as opaque. The exact timing unit resolution of this function is not specified on utime module level, but documentation for a specific port may provide more specific information.

This function is intended for very fine benchmarking or very tight real-time loops. Avoid using it in portable code. Offset ticks value by a given number, which can be either positive or negative. However, delta can be an arbitrary integer number or numeric expression. If the result is negative, it means that ticks1 occurred earlier in time than ticks2.

Otherwise, it means that ticks1 occurred after ticks2. If that does not hold, incorrect result will be returned. Informal rationale of the constraints above: Suppose you are locked in a room with no means to monitor passing of time except a standard notch clock.

To avoid this mistake, just look at the clock regularly. Your application should do the same.

Run tasks in steps, and do time-keeping inbetween. Polling with timeout. Scheduling events. But note that time may and will also overflow. Returns the number of seconds, as an integer, since the Epoch, assuming that underlying RTC is set and maintained as described above. If an RTC is not set, this function returns number of seconds since a port-specific reference point in time for embedded boards without a battery-backed RTC, usually since power up or reset.

If you want to develop portable MicroPython application, you should not rely on this function to provide higher than second precision. In CPython, this function returns number of seconds since Unix epoch, UTC, as a floating-point, usually having microsecond precision.

With MicroPython, only Unix port uses the same Epoch, and if floating-point precision allows, returns sub-second precision. Some embedded hardware also lacks battery-powered RTC, so returns number of seconds since last power-up or from other relative, hardware-specific point e. MicroPython 1.

Set manually by a user on each power-up many boards then maintain RTC time across hard resets, though some may require setting it again in such case.

I want to send data in the Graphite database with a Esp32 and for that I need the timestamp which must be in Epoch format.

I didn't know anything about Graphite until now but a quick web search found me the Graphite documentation :. Carbon-cache will use the time of arrival if the timestamp is set to A web search for unix epoch time quickly got me to a Wikipedia page which tells me:.

Using that knowledge you can calculate the timestamp you need from the value you get from RTC. Many embedded ports, including MicroPython, use Epoch time of January 1, It sounds like your're on a network so it should be easy to do.

My result was this number, It is integer seconds. With MicroPython there is no precision beyond seconds with this call. You can get microseconds using datetimebut that's in datetime not timestamp format. MicroPython ignores timezone.

Feedback on Q2 Community Roadmap.For example, imagine a relay that has to be activated at a certain time or a data logger that has to store values at precise intervals.

But these chips are not perfectly accurate so, you need to do manual adjustments over and over again to keep them synchronized.

The protocol can be used to synchronize all networked devices to Coordinated Universal Time UTC within a few milliseconds 50 milliseconds over the public Internet and under 5 milliseconds in a LAN environment. UTC does not vary, it is the same world wide. NTP sets the clocks of computers to UTC, any local time zone offset or day light saving time offset is applied by the client.

In this manner clients can synchronize to servers regardless of location and time zone differences. NTP uses a hierarchical architecture. Each level in the hierarchy is known as a stratum. At the very top are high-precision timekeeping devices, such as atomic clocks, GPS or radio clocks, known as stratum 0 hardware clocks. Stratum 1 servers have a direct connection to a stratum 0 hardware clock and therefore have the most accurate time.

Each stratum in the hierarchy synchronizes to the stratum above and act as servers for lower stratum computers. NTP can operate in a number of ways. The most common configuration is to operate in client-server mode. The basic working principle is as follows:.

Follow the next steps to install this library in your Arduino IDE. There should be a couple entries. Click on that entry, and then select Install. The following sketch will give you complete understanding on how to get current day and time from the NTP Server.
