Relative Dates

Lithium Alumni (Retired)

Hello again, fellow Lithosphereans,

As part of our continuous coverage of User Experience topics around Lithium Communities, we are happy to announce a little bit of incremental improvement that some of you have eagerly awaited for:

Introducing Relative Dates.

Summary: In our quest to make our UI friendlier and your communities' content feel even more relevant to your users, we now allow you to choose “Relative Dates” versus the standard numeric date stamp (starting with Lithium 9.0.3 and refined on upcoming 9.0.4).


What is so great about this feature?

Look at the standard experience of any board. Current dates are so precise that on a column, they need to be parsed one by one. They use numeric values, which do not allow for a webbed narrative or a contextual tie to the user’s concept of NOW.

So with the new feature, instead of this:

You have the choice to see this:

Which system does allow you to get a faster gauge of the content's freshness? Which method seems more natural to you or your community's audience? Independently of the answer, you have a choice for either one. I should note that Relative Dates do offer a quick tooltip on rollover displaying the precise date should you need it (so you can get the best of both worlds).

Because we believe that Relative Dates are more human-readable, It would be the default for all new communities, but because we don’t presume to know better than you... It will be off by default on upgrading communities. You can change it ether way.

 


Enjoy!

Now, for those of you that love this short of minutia, lets go on how we implemented it and how you can further customize it:
We adopted a decreasing granularity of relative dates, under the knowledge that the average context awareness becomes less precise over time.

Therefore:

 

  • Today (1st hour): Granular on minutes   
  • Today (Rest of day): Granular on hours   
  • Yesterday: Granular on AM/PM  
  • Rest of the week: Granular on days   
  • Rest of month: Granular on weeks
  • Rest of year: Granular on months


In Settings > Layout Settings > Date and Time Settings you will have a couple of useful choices:

 

1. You will be able to uncheck “Use Date Names” if you prefer day and month numbers instead of name.




If so chosen, instead of:


Saturday
Sunday
February
December 2008

You will get:

 

2 days ago
3 days ago
2 months ago
4 months ago

 

2. You will be able to choose the moment where to stop relative dates using “Relative Date Max Age (Days)

That way, you may decide to list the first month as relative, and anything older in numeric dates... Your call. Different people recall events and dates on different manner. Use what works best for your community.

Your settings, by the way, are specific to each board, and all associated content to that board (columns, messages, search results, etc) will adopt the standard chosen.

Since we are in the groove of date customization... Lets remember some of the powerful settings that were already available in your admin.
Independently of your use of Relative Dates, you can customize your date stamp in numerous ways:

In the Admin tool, at “Date Display Format” you can configure the MM-dd-yyyy string to achieve any desired effect (for those techy people in the audience: we adopted the Java SimpleDateFormat Class).

 

Letter Date or Time Component Presentation Examples
G Era designator Text AD
y Year Year 1996; 96
M Month in year Month July; Jul; 07
w Week in year Number 27
W Week in month Number 2
D Day in year Number 189
d Day in month Number 10
F Day of week in month Number 2
E Day in week Text Tuesday; Tue
a Am/pm marker Text PM
H Hour in day (0-23) Number 0
k Hour in day (1-24) Number 24
K Hour in am/pm (0-11) Number 0
h Hour in am/pm (1-12) Number 12
m Minute in hour Number 30
s Second in minute Number 55
S Millisecond Number 978
z Time zone General time zone Pacific Standard Time; PST; GMT-08:00
Z Time zone RFC 822 time zone -0800

 

The letters in the string can be repeated to control the abbreviation or extent of the information.

"EEE, MMM d, ''yy" Wed, Jul 4, '01
"h:mm a" 12:08 PM
"hh 'o''clock' a, zzzz" 12 o'clock PM, Pacific Daylight Time
"K:mm a, z" 0:08 PM, PDT
"yyyyy.MMMMM.dd GGG hh:mm aaa" 02001.July.04 AD 12:08 PM

"yyMMddHHmmssZ" 010704120856-070

You can see how this could be quite helful in order to localize your dates (to European format for example). For further information on that topic, visit the source documentation at Java support pages.
