When i look at the various channels and Date/Times in the BasicUI, all of the Astro2 items show with a format of:
YYYY-MM-DD HH:MM And the Hour is in 24hr format.
Is possible to change this default format? I did change the format within the NTP binding, but that did not seem to make a difference.
Is there an option in the Astro2 binding to set the default format?
You can change that in your items label definition:
DateTime Sunrise_Time "Sonnenaufgang [%1$tH:%1$tM]" ...
Text item=Sunrise_Time in your sitemap will show in this case:
For other definitions look for ājava date time definitionsā in your favorite search engine.
Yes, I figured you can change the format with an items file and custom format. But that would also require defining an custom item for each and every existing astro item with a custom date and time format.
I was just hoping maybe you could set a default for all items in the binding so the default paperui date time could be changed.
Iām almost certain thatās not possible. However itās okay I guess because sunset will be a time, next full moon maybe a date and the next solar eclipse will consist of a year. It doesnāt hurt to define it.
Maybe this will help:
You only have to define it for the Channels you are actually using AND want to display on your sitemap. For most practical purposes that will only be a few.
Iām intrigued by a user configurable default for all DateTime Items. Most users will want to display the majority of their DateTimes in the same way (though @ThomDietrich appears to have gone all out 
). Iām not sure how feasible that is in the current sitemap architecture.
What is? Back when I build my astro items file, this took me 10 minutes tops. Itās just a bit of copy&paste really. Have it once, forget about it. What you do in rules or sitemaps is unrelated from that point on forward.
How did you get the āemotesā in to your map?!
Could you define āgetā? You just copy them in there.
What I meant was I donāt know how feasible the current sitemap architecture can support something like setting a default date time format. I agree it really isnāt a significant about of work to copy paste the labels.
When i copy your āCodeā in to sublime all emotes are gone 
thatās why i asked^^
Create a new file inside sublime and try again 
The file you are trying to write to is probably not in Unicode but ASCII encoding. ASCII doesnāt know emojis.
You can change that by opening your old file and selecting āFile -> Save with Encodingā inside sublime.
Quick question after setup the 2 things moon and sun and create the the astro.sitemap astro.items and astro.map
Do I have to set up something more? 
cause i did not get your example to work o.O
I also changed the channel from your āhomeā to my right local one
{ channel="astro:sun:local:set#start" }
In the spirit of the Tutorials and Examples category I have just posted the above example to itās own thread. Astro Items+Sitemap+Map+ā Binding Example
It was not really ready to be presented to others but hey, whatever.
What does not work? The simple elements like the sunset/sunrise should be visible right awayā¦
