The error message is correct: there is no 03:30 in Kiev time on 2014-03-30. Kiev switched from UT+2h to UT+3h at 01:00 UT, jumping from 02:59 to 04:00 local time. >I have datetime, stored in "UTC" and have some periodical task (period 1 day). >Then i have a customer - for him information must be viewed in??'Europe/Kiev'. This part is no problem. Each UT time corresponds to a definite Kiev local time; you can always perform this conversion. The code that you quoted doesn't perform conversion; you need to create a DateTime with time_zone=>"UTC" and then set_time_zone. >But he want that task will execute in 00:03:30 in his local timezone. Presuming you mean at 03:30, this is not possible for Kiev on 2014-03-30. In general, it is not possible to do something at a fixed local time every day; there's always some day and locality for which that local time doesn't exist. In the extreme, there are cases such as Christmas Island (Pacific/Kiritimati) on 1995-01-01, where local time skipped the entire calendar day as the island switched from the eastern side of the International Date Line to the more fashionable western side. You must select some alternative behaviour to follow on days when the desired local time doesn't exist. -zefram
