dvb-apps fails to build with glibc 2.31 with the following error:
| dvbdate.c: In function set_time:
| dvbdate.c:312:6: warning: implicit declaration of function stime; did you mean ctime? [-Wimplicit-function-declaration]
|   312 |  if (stime(new_time)) {
|       |      ^~~~~
|       |      ctime

this patch takes from the first entry in the reference fixes it.

Hello,

Thanks for the patch. There are however a few coding style issues.
First, the commit title must always have the following format:

	package/<foo>: <something>

I.e you forgot the package/ prefix.

Please add a reference to the autobuilder failure, like this:

All patches must have a description and Signed-off-by.

Could you fix those details, and send an updated version? Thanks a lot!

frankly speaking, I had no idea this issue was marked by the autobuilder, I've encountered it when trying to build an image with dvb-apps installed.

I'll reference the failure in my next revision.

as mentioned in the commit mail, I took the patch as is from the first reference.
I'll try to find a more detailed commit or will rewrite it.

Thanks,

No problem. But when you have a failure, it makes sense to check if we
have encountered it in the autobuilders. You can easily search by doing
this:

	http://autobuild.buildroot.org/?reason=dvb-apps%

The % at the end is important, as it acts as a wildcard.

And if the failure was not found by the autobuilders, it is interesting
to investigate why. Is it because the failure is related to a very
specific system configuration? Or an architecture/toolchain combination
we are not testing?

Best regards,

Thomas
