tomorrowdaylength tag

I'm wondering about the <#tomorrowdaylength> tag
Tomorrow will be 4min 40s longer than today
There are always 24 hours in a day, surely (give or take a millisecond a year)
Would it be better to say something like...
There will be 4 mins 40s more daylight tomorrow
Or am I missing what it is trying to tell me?

No, you're absolutely right!

Fair point. But people do tend to say "the days are getting longer". But your suggested version is much clearer than the existing one; I'll change it.

David, strangely enough, not five minutes ago a friend was commenting on my weather website and made that very remark.
Actually, is that tag measuring the change in the length daylight, or the amount of time between sunrise and sunset? Both are expressed in the almanac.

Hello All
My first reply in the forum, after nearly a year as member.
Why not only let the <#tomorrowdaylength> tag be xxmin yys,
then I can write, in my words, what it means ( in Danish ).

The French weather bulletins show a panel at the end which gives the name of the saints day for tomorrow, sunrise, sunset and how many minutes longer tomorrow will be than today! So they use that wording, but it stood out last night.

Yes indeed, it should really have been like that in the first place. As with many things, I have no idea why I did it this way

. There should be two extra tags, I think, one with just the minutes and the other with just the seconds.
Except that the whole thing is broken anyway and I should probably just remove it

Steve, please don't remove this webtag. I really prefer having this information no matter how it comes across. I think most people can decipher that it means daylight length is changing. Consider rephrasing perhaps but not removal.
Thanks

It's not so much the phrasing, it's the fact that it's actually wrong!

Ah, sorry; I thought everyone knew it was deficient, as we discovered at the solstice.

I like this feature and didn't know it was wrong as I wasn't using the system at solstice. How wrong is it?!

The data Cumulus supplied for the webtag matches the data WeatherUnderground posted on their page. At least for my location.

The problem as I understand it is that the library routines I use for calculating length of daylight etc are apparently accurate to the nearest minute, which is fine for most uses, but when you start subtracting today's from tomorrow's and displaying it to the nearest second, it's meaningless. At the Winter solstice, Cumulus was still saying that the following day would be shorter by a few seconds.
But it's interesting that Wunderground says that tomorrow for me is 5m 8s longer and Cumulus says 5m 7s longer, so maybe I don't understand the problem after all.
Also of interest, perhaps, is that Wunderground also uses the "Tomorrow will be x longer" phrase.
