By "similar" you mean "identical", no?
Why is the rtc subsystem not just using the generic time64_to_tm()?
Yes, yes, I realize that due to historical mistakes, there's a duplicate 'struct rtc_time' struct, but it turns out that that is _identical_ to 'struct tm' except it also has a 'int tm_isdst' at the end.
So you could literally make a union of the two, pass the 'struct tm' part down to the generic code, and just do
rtc_tm->tm_isdst = 0;
at the end.
Rather than have a duplicate copy of that admittedly clever Neri and Schneider algorithm.
Hmm?
