Hi, I have video files (FAT) that are taken in a different timezone than my current location. The modification date/time in the metafila data of the video file shows the time video was taken, although in the current timezone of my computer, if I understand right.
I wish to convert the date/time to the origin. The video was taken in London, Ontario Canada at 2015-06-21 07:53:28, when looking at the metadata of the file on my computer (timezone "Europe/Berlin") it says modification date "2015-06-22 01:53:28". Hence, there is a 6 hour difference between the two time-zones I use the script provided here: http://blog.revolutionanalytics.com/2009/06/converting-time-zones.html pb.txt <- "2015-06-22 01:53:28" #modification date as shown on my computer (timezone "Europe/Berlin") pb.date <- as.POSIXct(pb.txt, tz="Europe/London") pb.date <- as.POSIXct(pb.txt, tz="America/Toronto")#timezone of origin video camera location format(pb.date, tz=local.time,usetz=TRUE) #formats the mtime to data and time when the video was taken [1] "2015-06-22 07:53:28 CEST" # the time is correct but the date is wrong as it has added 6 hours rather than subtracting. I find working with different time-zones to be difficult, I hope I managed to formulate an understandable question.
