[BLU/Officers] Boston Linux Meeting, Wednesday, August 16, 2017 - Federico Returns

[John Abreau]

Hi, Bill.

The script uses Data::ICal to generate the results, and I had hard-wired it
to use an offset of '-0500'.

I just modified it to check if a date was DST or not, and put either
'-0400' or '-0500' in a variable, then use that variable to specify the
offset:

However, instead of correcting the time, it's truncating it:

                    dtstart => Date::ICal->new(
                        day => $date[2], month => $date[1], year =>
$date[0],
                        hour => $start[0], min => $start[1], sec =>
$start[2],
                        offset => '-0500')->ical,

yields

    DTSTART:20170817T010000Z

but

                    dtstart => Date::ICal->new(
                        day => $date[2], month => $date[1], year =>
$date[0],
                        hour => $start[0], min => $start[1], sec =>
$start[2],
                        offset => $offset)->ical,

yields

    DTSTART:20170817Z

I'm not sure why.

To check for DST, I'm doing the following:

        my $time = timelocal(0, 0, 0, $st[3], $st[4], $st[5]);
        my ($dst) = (localtime($time))[8];
        $offset = $dst ? '-0400' : '-0500';

Any ideas why this is failing and what I need to do to fix it?

Attached is the cgi script, with database password modified.
