When people post/answer questions here, time stamp doesn't show the year. I think the year in time stamp is very important. Technology and solution change fast . It will be helpful to add the year in time stamp. It will help people to filter information that are outdated.. Thanks!
The year will appear if you hover your mouse over the date.
The timestamp "ages" gracefully so that as a post gets older, the timestamp shows more information about when it was asked/answered. If a timestamp is missing information, you can assume that it is the most recent "whatever" corresponding to the date fragment -- year, month, day, as appropriate. As others have noted, you can always hover over the timestamp to get the full date and time.
