This is aimed at folks who have never done any coding, like me. It's not very difficult.
Well, if you go to the Customwps Wiki page:http://www.rockbox.org/twiki/bin/view/Main/CustomWPS
and read all of the tag descriptions under Real Time Clock as well as alignment ones %al etc and then look at the hint below:
"For example, I use: %ca, %cb %cd, %cH:%cM:%cS"
Then look at the posts on this page from Johnson4 and Ddyourself and the code:
%al%cb %ce, %cH:%cM %ar%pvdb %bl%%
I went back to the Customwps page above and looked up the tags.
I like the Ajax wps as it's easy to read, shows how much time has played in the song, how much is left, the current song, the next song, volume level and so on. I went to the .rockbox folder, wps and opened Ajax.wps with notepad. On the 8th line down or 5th after the comments, I found the offending line:
%al%ca, b dc%ar%cl:M:Sc
It's a little difficult to divine the Ajax creator's intentions as I don't have the old code but by mixing and matching the code above, I replaced it with:
%al%ca, %cb %cd, %cH:%cM:%cS %ar%bl%%
Which gives you the month and date, day of the week, time and battery level.
It works. Just replace the 8th line with my line or further modify it yourself.
