I have looked at it a bit longer, and have created the following patch
for timezones.pl
46c46
< # in milliseconds since midnight in local standard time
---
> # in milliseconds since midnight in local wall time
59,62c59,61
< $millis += $rawoffset;
< } elsif ($6 =~ /w/) {
< print STDERR "$timezonename not in standard time\n" if
$stdoffset;
< $millis -= $stdoffset;
---
> $millis += $rawoffset+$stdoffset;
> } elsif ($6 =~ /s/) {
> $millis += $stdoffset;
298c297
< my $startrule = parseRule($rawoffset, $savings,
---
> my $startrule = parseRule($rawoffset, 0,
The routine parseTime was parsing time with respect to standard time,
while the default input for SimpleTimeZone is in wall time. I have
changed this. There probably is a different way to patch this, but I
guess this is the fastest.
$stdoffset=$savings is the offset with respect to standard time just
before the end of DST.
$stdoffset=0 is the offset with respect to standard time just before the
start of DST.
When the suffixes g, u or z are present, to get wall time, the total
offset with respect to UTC, $rawoffset+$stdoffset, must be used.
When the suffix s is present, to get wall time, the offset with respect
to standard time, $stdoffset, must be used.
When no suffix is present, wall time is assumed.
I am no expert on this, so please correct me if I'm wrong. I have tested
this on EU and America/Santiago and Pacific/Easter.
Kind regards,
Bastiaan Huisman
