NTP Binding - Formatting DateTime

Setup, Configuration and Use Beginners

Hello,

I’m using openHAB 2.4 and looking at the NTP binding documentation here:

My things and items are defined per the documentation and listed below.

ntp.things

ntp:ntp:demo  [ hostname="us.pool.ntp.org", refreshInterval=60, refreshNtp=30 ]

ntp.items

DateTime Date  "Date [%1$tA, %1$td.%1$tm.%1$tY %1$tH:%1$tM]"  { channel="ntp:ntp:demo:dateTime" }

Am I missing something or should the Java documentation for formatting link point to:

https://docs.oracle.com/javase/8/docs/api/java/util/Formatter.html

Right now it doesn’t seem appropriate as it it points following which doesn’t seem to work for me.

https://docs.oracle.com/javase/6/docs/api/java/text/SimpleDateFormat.html

That link results in a 404 error.

The second one (SimpleDateFormat (Java Platform SE 6)) is correct.

Oops poor copy and paste.

https://docs.oracle.com/javase/8/docs/api/java/util/Formatter.html

The above should work. My point is this the following table doesn’t produce usable results-- at least for me. Before updating the wiki, I’d like a sanity check. Perhaps my installation is wack somehow.

You’ll need to define what you mean by “doesn’t work”. Maybe include the actual result that you’re thinking is wrong…

Hi,

I want my sitemap to display the date and time like this:

This configuration gets me there

default.sitemap

sitemap default label="My Home" {
    Frame label="Current Date and Time" {
        Text item=Date
    }
}

ntp.things

ntp:ntp:demo  [ hostname="us.pool.ntp.org", refreshInterval=60, refreshNtp=30 ]

ntp.items

DateTime Date   "[%1$tA, %1$tB %1$td, %1$tY — %1$tl:%1$tM %1$tp]"  { channel="ntp:ntp:demo:dateTime" }

However, if I follow [https://docs.oracle.com/javase/6/docs/api/java/text/SimpleDateFormat.html,

ntp.items looks like this:

DateTime Date   "[%1$tE, %1$tM %1$td, %1$ty — %1$th:%1$tm %1$ta]"  { channel="ntp:ntp:demo:dateTime" }

Translated that should equate to:

`E` Day in week [Text] - Example `Saturday` ;  `Sat` 
`M` Month in year [Month] - Example `January` ;  `Jan` ;  `01`
`d` Day in month [Number] - Example `5`
`y` Year [Year] - Example '2019` ;  `19`
—
`h` Hour in am/pm (1-12) [Number]- Example '8`
`m` Minute in hour [Number] - Example `05`
`a` Am/pm marker [Text] - Example  `PM`

Instead of the desired output, I get this:

You’re right, that’s a defect in the README. The original OH1 README correctly points to the Formatter class instead of the SimpleDateFormat class.
