Hi, I am using Nexus 4 with Android 4.4.4.
I am using Google calendar and Business calendar and both of them are affected so I suspect that the problem is in the database. I also found the problem in other phones.
The problem occurs between 6th October to 26th October and in similar periods in the next years.
I want to add that the Israeli parlament changed the DST to end on 26th October instead of 5th October (changed since 2013) so I think that Google Timezone DB has not been updated correctly.
Thank you very much.
