Where is time stamp message for Echo extension?

Have a look at this thread. You could try to translate the "time-ago" messages in MediaWiki core. These are:

• Seconds-ago (“$1 {{PLURAL:$1|second|seconds}} ago”) Minutes-ago (“$1 {{PLURAL:$1|minute|minutes}} ago”) Hours-ago (“$1 {{PLURAL:$1|hour|hours}} ago”)
• Weeks (“{{PLURAL:$1|$1 week|$1 weeks}}”) Months (“{{PLURAL:$1|$1 month|$1 months}}”) Years (“{{PLURAL:$1|$1 year|$1 years}}”) Ago (“$1 ago”)

It would be useful to get some feedback on what translating these does to the situation. It appears from the thread that it hasn't yet been confirmed whether these strings are actually used in Echo extension or not.

Hello Lloffiwr,

thank you for your answer. The messages you mentioned have been already translated, both for Upper Sorbian and for Lower Sorbian. They appear translated among the system messages on Wikipedia. Strange, how it is in Welsh Wikipedia?

Regards,

Hmm. Then maybe these messages are coming from CLDR as suggested by Nike.

If that's the case I understand that it is still untranslated. The Sorbian languages are not a part of CLDR yet.

If you have a page showing the message, append the parameter uselang=qqx to its URL (preceed by either ? or & depending on whether ? is already there) and you get the message keys instead of the message contents.
