Dashboard Activity dates conditionally need the year

[GaryJ]

If you import the Theme Unit Test data, one of the posts is scheduled for Jan 1st 2050. The Dashboard Activity widget doesn't indicate what year this is scheduled for though, and leaves the date as ambiguous - I suspect most people would assume it would be in a few weeks time, given no other information. The same would apply if the Recent Activity doesn't have a limit on it, where the last post was more than a year ago.

Since these might be moving towards edge cases compared to activity on a lot of sites, I'd like to see a year included only if the timestamp is more than 1 year before or after the current date (rather than on each date).

Screenshots included for clarification.

Trunk - years not shown on dashboard activity widget.

[GaryJ]

Suggestion - include years where timestamp is more than 1 year before or after the current time.

Probably the most logical thing to do is to display the year if the post date's year is not the same as the current year.

[GaryJ]

Show date if timestamp difference is greater than 1 year

[GaryJ]

Show year if timestamp has different year to now.

Two suggestions offered:

• 26502.diff​ goes with a difference in the timestamp of more than one year, as per original ticket description.
• 26502-alt.diff​ goes with johnbillion's (probably more sensible) suggestion of showing the year if it's not the same as the current one.

Refreshed the alt patch (johnbillion's suggestion)

[chriscct7]

Refreshed the patch. Good to go.
