Follow-up Comment #1, bug #46303 (project avr-libc):
I think the bug is not fixed. eu_dst() tells me that DST does not apply on
2015-10-24 01:00:00 UTC. But it should.
>From eu_dst() :
/* determine mday of last Sunday */
n = tmptr.tm_mday - 1;
n -= day_of_week;
n += 7;
d = n % 7; /* date of first Sunday */
n = 31 - d;
n /= 7; /* number of Sundays left in the month */
d = d + 7 * n; /* mday of final Sunday */
If we try with tmptr.tm_mday == 25 and day_of_week == 0 (for October 25th,
which is the last Sunday of October in 2015), then we get d == 31. Which is
actually the last Saturday of October.
