Hi guys, I need your expertise on that.
I have a column with dates and time (see attached) which is in Local Time Zone (Europe/Athens) and I want to convert it to UTC. I know this is pretty straight forward but the problem lies here:
If you notice on the attached .xlsx, arrows between 25103 and 25104 are missing the date 29-Mar-2015 03:00:00. That is because the weather station was using Daylight Saving Time for the entire year (UTC+0300), and I tried to change that and keep UTC+0200 for wintertime. Therefore I missed 29-Mar-2015 04.00 (which was the time that Greece changed from UTC+0200 to UTC+0300) and I have a double entry for 25-Oct-2015 03.00 ( (which was the time that Greece changed from UTC+0300 to UTC+0200).
When I try to go from LT to UTC with
LT.TimeZone = 'UTC';
I am losing information about the two errorous dates I mentioned (29-Mar-2015 03:00:00 and 25-Oct-2015 03.00). Which means that I am creating a column with all dates starting from 31/12/2014 21.00 to 31/12/2015 22.00.
Is there a solution to my problem? I would appreciate your thoughts...
