Hello!

I'm trying to import an Office365 ical file and keep getting this error:
DateTimeZone::__construct(): Unknown or bad timezone (tzone://Microsoft/Utc)

My timezone in Office365 is: "(UTC+01:00) Amsterdam, Berlin, Bern, Rom, Stockholm, Wien"

In iCalImport.php I used:

$wtzdata["Amsterdam, Berlin, Bern, Rome, Stockholm, Vienna"] = "Europe/Amsterdam";
$wtzdata["(UTC+01 Amsterdam, Berlin, Bern, Rom, Stockholm, Wien"] = "Europe/Berlin";
$wtzdata["Mitteleuropaeische Zeit"] = "Europe/Berlin";
$wtzdata["UTC+01"] = "Microsoft/Utc";
$wtzdata["Microsoft/Utc"] = "Europe/Berlin";

The ical file is: https://outlook.office365.com/owa/calendar/793627907a754b0994c0835e9d90ac7e@stshef.eu/06b4df365b914d52853298f7411baf8417417192149852592007/calendar.ics

Thanks for any idea
Hello,

You need to use:

$wtzdata["tzone://Microsoft/Utc"] = "Europe/Berlin";

Good old Microsoft using a completely random timezone! hehe

Many thanks

I'm sorry to report again with the same error here.
In the past few days, the calendar could again display the error message:

DateTimeZone :: __ construct (): Unknown or bad timezone (Customized Time Zone)

My timezone in Office365 is: "(UTC+01:00) Amsterdam, Berlin, Bern, Rom, Stockholm, Wien"

In iCalImport.php I used:
$ wtzdata ["(Customized Time Zone)"] = "Europe/Berlin";

Hello,

So the issue still occurs even though you have added the code into iCalImport.php ?

Can you check if the iCalImport.php contains

<?php at the start

and $ wtzdata

is actually

$wtzdata

If so, can you provided a copy of the iCal Event file so we can test the import?

Many thanks
Tony

Thanks for the hint.
I was able to fix the problem with the following entry:

$wtzdata ["Customized Time Zone"] = "Europe / Berlin";

Thank you for your support!
