[horde] daylight event one hour more

[Denis Gabriel Ignacio]

Hello

I have a problem with daylight saving time, When the scheduled events  
recurrent weekly and sent within daylight period. The invitation time  
is displays with one hour more.

If the invitee opens the invitation on another email client (eg  
thunderbird) the invitation displays the correct time.

For events scheduled outside daylight period, the time is ok


The following is an example of ics files. One with the sample file  
generated inside daylight period  
(event-invitation-inside-daylight.ics) and another generated when the  
event is scheduled outside  
daylight(event-invitation-outside-daylight.ics).


We tested in a couple web browsers and the result is the same for all.

horde 5.2.13
kronolith 4.2.19
imp 6.2.17
horde_Icallendar 2.1.4

Server
Centos 6.5
PHP 5.6.10
Timezone America/Sao_Paulo (php.ini)
Apache 2.4
