problems in datetime and minute-abbr when changing language

[JLJ5]

Hi, I am changing the language to Spanish. At first there where some words that were not included in the package, but I added them into lang.php and it worked almosto for all, but it did not when I try to get datetime-text and minute-abbr.

I got a "panichd::lang.datetime-text" and "panichd::lang.minute-abbr", instead of the calendar and last update info.

Any idea on how to solve it? Thanks!
