IMX8M yocto linux NTP bug (aka Y2K38)

agmc1971 — Mon, 19 Apr 2021 15:52:18 GMT

Hello,

my IMx8M yocto (SUMO) linux microcontroller evidence a problem in setting date/hour using NTP service if the system clock (RTC) have a date beyhond the 2038. If I write the year that is less than that date , NTP succeed to setting the right date/time.

Do you experienced similar issue, and if yes, what is the solution to this bug?

Thanks in advance for your help!

Best regards,

The solution is to use the latest yocto version: "Dunfell".

In that version the bug has been fixed.

Actually Linux starting with version 5.6 has 64-bit time_t (the type is used for the time) even on 32-bit architectures.
Now I see dates after the year 2038 are supported:

root@imx8mqevk:~# date 050113132222
Wed May 1 13:13:00 UTC 2222
root@imx8mqevk:~# date +%s
7962757988
root@imx8mqevk:~# touch file
root@imx8mqevk:~# ls -l --time-style=+%s file
0 -rw-r--r-- 1 root root 0 7962757992 file
