Cumulus Support

you can not put a tag that marks the difference between the present day and tomorrow simply expressed in hours and minutes, instead of the string as the cumulus ex. (tomorrow, +00 m - 26s)

Possibly. Actually, some time ago I was going to remove the tag altogether, as it's not very accurate, particularly around the solstices: http://wiki.sandaysoft.com/a/FAQ#Today_ ... r.2Flonger

I was asked to leave it in, but I don't plan to spend any more time on it. You could parse the string using javascript; you haven't made it clear exactly what it is you want to see instead.

how could I do? I compose you the string in javascript

Use split() to extract the elements of the string - http://www.w3schools.com/jsref/jsref_split.asp

Then use the parts with the minutes and seconds to make your own string.
