[yocto] Fwd: How to make the os-release package work with local walltime instead of GMT?

[Davis Roman]

Hello,

I'm trying to fullfill a requirement which states that I must have a file
in my root filesystem which has the timestamp of when the rootfs was
generated for traceability purposes.

I've included the os-release package into my image recipe.

However, when I cat /etc/os-release, I notice that the BUILD_ID variable
does not reflect the actually time that my build took place.

Upon further inspection, I noticed in the os-release recipe that BUILD_ID
is based on the DATETIME variable.

Drilling down further, I noticed that DATETIME is defined
in ./meta/conf/bitbake.conf

    DATE := "${@time.strftime('%Y%m%d',time.gmtime())}"
    TIME := "${@time.strftime('%H%M%S',time.gmtime())}"
    DATETIME = "${DATE}${TIME}"

So it appears to me that DATETIME is based on gmttime.

Instead, I would like this to be based on wall time.

Any suggestions on how to do this?

Thank you,

Davis
