Time wrong on ics feed import

My problem which started with version 2.5.0 of this plugin. I have reverted to version 2.4.1 on the live website as a workaround, but would love to upgrade to the latest version of the plugin.

All imported events, no matter what their starting time in the ics feed appear to start at 11pm the night before. I have tried both states of the “Convert event’s date/time to calendar’s timezone” with the same problem result.

Timezone on the feed and in WordPress is Australia/Sydney.

An example ics feed is here: http://r.elvanto.com.au/fullcalendar/0a0284d0-7ab7-11e3-9edb-094b5ffbcb0b/7967ee6c-a1bf-11e3-9edb-094b5ffbcb0b.ics

The resultant problem calendar is here: http://narrabrianglican.org/wptest/calendar/

Forgot to mention that in the test I am currently using v2.5.11 of the plugin and the problem is still present.

Hi,

I see “TZOFFSETFROM:+1000 / TZOFFSETTO:+1100”, and it should be “TZOFFSETFROM:+0100 / TZOFFSETTO:+0000”, can you access and edit http://r.elvanto.com.au calendar?

I still have two questions:

1. The same ics feed into v2.4.1 of the plugin produces the correct output, however any v2.5.x version always produces times of 11pm the night before the day of the event, no matter what the event time is in the ics feed. If it was just a number of hours difference, the times would vary with the feed times.

2. If the offset you mention is the problem, Why does the old plugin version behave differently to the new one with the same feed?

I realised I didn’t answer your question. Can I change the elvanto.com.au feed? The answer is not easily, this feed is provided by a third party.

On reference to RFC5545, the standard for ics feeds, I quote:

The mandatory “TZOFFSETFROM” property gives the UTC offset that is
in use when the onset of this time zone observance begins.
“TZOFFSETFROM” is combined with “DTSTART” to define the effective
onset for the time zone sub-component definition. For example,
the following represents the time at which the observance of
Standard Time took effect in Fall 1967 for New York City:

DTSTART:19671029T020000

TZOFFSETFROM:-0400

The mandatory “TZOFFSETTO” property gives the UTC offset for the
time zone sub-component (Standard Time or Daylight Saving Time)
when this observance is in use.
