Thanks for your advice. I've started with using xLabel to display date and time but met the same problem with date string localization. The problem is possibly caused by using not unicode functions to get and display date/time strings. I'd like to make some changes in xLabel but cannot find sources for version 3.3.8 (it's very important for me to use this version). Only 3.3.7 and 3.4.2 are available. Do you know where can I get the sources?
