In my latest firmware Android zoneinfo database is up to date (tzdata2012b) - I am not sure I really understand what you are saying here. According to
http://www.timeanddate.com/worldclock/city.html?n=136 London GMT+1 is exactly right due to daylight saving.
I did not put "Google Play" into firmware and I do not have it on my reader. In addition I have no idea where to get one you are using. So I am afraid you are on your own - would like to hear any information on this however, may be it is not totally useless on the reader after all
