I changed viewcolumns to: set viewcolumns=-{name}..,{mtime},6{} in the vifmrc to display the time modified. When I launched vifm it displayed the column in the format mm/dd hh:mm. I'd prefer the format yyyy-mm-dd hh:mm. I went looking around for information on how to format the date and I couldn't find anything. Can this be done and if so how?
