Dear Maintainer,
With the following program (test.awk):

{print fix_time($0)}
function fix_time(tstr) { # tstr=time string field
if (length(tstr) != 21 || !tstr) {
return tstr
} else {
Y=substr(tstr, 2, 4)
M=substr(tstr, 7, 2)
D=substr(tstr, 10, 2)
h=substr(tstr, 13, 2)
m=substr(tstr, 16, 2)
s=substr(tstr, 19, 2)
t=mktime(sprintf("%s %s %s %s %s %s", Y, M, D, h, m, s))
return strftime("%Y-%m-%d %H:%M:%S", t)
}

Daylight savings for my local time zone (Central Time) started on
2012-03-11. Time is not interpreted correctly for the second hour of
the day when daylight savings starts.

Hello,
Thanks for your bug report. While the current behavior is surprising,
there is nothing gawk can do about it. The mktime functions is simply
a wrapper around the C/POSIX function with the same name and by design
has the same semantics. This function even explicitly allows out of
range values, as documented in the gawk man page. In comp.lang.awk I
see Geoff Clare reaching the same conclusion.
Regards,
Jeroen Schot
