Force English on date and have an option for 12/24 hour clock

Hey, those are 2 questions that I thought that will be popular in this forum but I didn't find any answers so I will ask those myself: I uploaded a watch face to Connect IQ shop and got many messages that asked for a setting for 12/24 hours format and messages that asked for the date to be shown if the system language isn't English. I think I need to add those 2 features to the watch face but I didn't find anything that will help me in the forum or the programmer's guide. To make it easier for you to help me with that case I am adding anything related to the date shown and the clock time to the code here: https://pastebin.com/ZQAJG2Pw.

I've seen a post in this forum about the 12 and 24 hours display but I didn't really understood the answer of how to do it. I've also seen that in the known watch face they used strings to override the date to get what they wanted but again I didn't manage to understand how to use it in my watch face and looked complicated to me.

Thanks to everyone that will try to help me here in advance!

Two things here. If you use custom fonts, you need to included all possible caracts for those dates to use Time.Gregorian data.

As far as 12/24, it's easy to see the setting on the watch:

System.getDeviceSettings().is24Hour;

Consider this simple function where is24Hour is set based on the above.

    function make1224(hr) {
    	var myHr=hr;
    	var myAmPm="";
        
        if(!is24Hour) {
			myHr = hr % 12;
            myHr = (myHr == 0) ? 12 : myHr;
            myAmPm= (hr>=12) ? "p" : "a";
        }	  
    	return [myHr,myAmPm];
    }

Hey jim, does this function need to be located inside the onUpdate()?

jim_m_58 over 5 years ago in reply to Kfir Eliyahu

It needs to be called in onUpdate when you get the time. Then pass the hour, and you get back the 12/24hours and am/pm in the case of 12hr.

What does it means being called in? I can't get it in the onUpdate() function unless I remove the first and last line of it I believe

jim_m_58 over 5 years ago in reply to Kfir Eliyahu

It means that in onUpdate() you can call make1224Hour() and pass the current hour.

sorry jim I still didn't understand it. I tried to use in in the onUpdate but I've got tons of errors and I feel like I did something wrong and it is not what you have meant.

Here's where I added the function make1224(hr): https://pastebin.com/YhAAandN

Here's what's going on in the code for the basics:

Take clockTime's hour (from clockTime=System.getTime() and save it to another var

var hr=clockTime,hour;

if 12 hr mode, do hr%12. This will give you a number between 0 and 11. Then is it's 0, make it 12.

I thought I got it this time after entering this:

    function onUpdate(dc as Dc) as Void {
        dc.setColor(Graphics.COLOR_BLACK, Graphics.COLOR_BLACK);
        dc.clear();  		
        var clockTime = System.getClockTime();
        var hr = clockTime.hour;
        var myHr=hr;
    	var myAmPm="";
        
        if(!System.getDeviceSettings().is24Hour) {
			myHr = hr % 12;
            myHr = (myHr == 0) ? 12 : myHr;
            myAmPm= (hr>=12) ? "p" : "a";
        }	  
    	return [myHr,myAmPm];

but I got a black screen (btw I used !System.getDeviceSettings().is24Hour because when I used !is24Hour it said symbol not found)

Take out the return on line 14, and use myHr when formatting/displaying the time.

Thanks a lot jim!

it works but there are some things I think shouldn't be like that:

1. only when the hour is 13:00 it turns to 1 in the 12 hours display

2. there's no AM or PM in the 12 hours display

3. there's no leading 0 but from what I've seen in the other discussion it needs to be like that although I want to get an option for this too if it is possible.

Really appreciate the help until now!
