Date picker in settings issue (UTC?) or my mistake?

hi mates,

so i did a function which calculate in days/hours/minutes the time between now and since/until an event.

So far, no issue, but i've just had a complain about time offset.

we are ok that the date picker in settings is in UTC time?

and time.now.value also?

here is my code:

function DayCount(){
	    if (CheckHours()==2400){return "INVALID TIME";} else {
	    	var NOW = Time.now().value(); 
	    	//var TZO = Sys.getClockTime().timeZoneOffset;
	    	var PastFutur = App.getApp().getProperty("ED")+CheckHours();//-TZO;
	    	var T =0;
	    	var PF="";
	    	if (PastFutur<NOW){
	    		T = NOW.toNumber()-PastFutur.toNumber();
	    		PF = "+";
	    	} else {
	    		T = PastFutur.toNumber()-NOW.toNumber();
	    		PF = "-";
	    	}
	    	var D = Math.floor(T/86400);
	    	var H = Math.floor((T - D*86400)/3600);
	    	var M = (T -D*86400 - H*3600)/60;
			return PF+D.format("%02d")+"  D -"+H.format("%02d")+":"+M.format("%02d");
		}
    }

    function CheckHours(){
    	var HM = App.getApp().getProperty("ET").toString();
    	if (HM.toString().length()!=5){return 2400;}
    	else if( HM.substring(0, 2).toNumber()>23){ return 2400;}
    	else if( HM.substring(3, 5).toNumber()>59){ return 2400;}
    	else { return (HM.substring(0, 2).toNumber()*3600) + (HM.substring(3, 5).toNumber()*60);}
    }

so when i test on mine (i'm utc+1), no problem at all.

but few users reported time offfset and everytime it is the utc offset,

i did again a test on simulator and i do have offset too (+1h for me) but not on my device.

do you see something wrong in my code?

have a great day

hi,

in case it can help others, here is how i do now

the only bug is due to DST since timeZoneOffset only works for current time (and .dst also)

function CheckHours(){
var HM = App.getApp().getProperty…

I've not really looked at your code, but I'm guessing you want the time from a different time zone. Here's a really simply way to do that given a UTC offset in hours.

var now=Time.now().value(); //seconds since 1/1/1970 00:00 UTC
System.println("utc="+hms(now));
var mst=now+(-7*3600); //us mst (utc-7)
System.println("mst="+hms(mst));
var est=now+(-5*3600); //us est (utc-5)
System.println("est="+hms(est));

where hms() returns a string of hh:mm:ss, using "seconds today" for that tz:

    function hms(secs) {
    	var h,m,s;
    	var dSecs=secs%(24*3600);	//only use "today" seconds
    	
    	h=dSecs/(3600);
    	m=(dSecs-(h*3600))/60;
    	s=dSecs%60;
    	
    	return h.format("%02d")+":"+m.format("%02d")+":"+s.format("%02d");
    }

output is:

utc=11:20:59
mst=04:20:59
est=06:20:59

you can do a similar thing with days if everying is based off the value() for a time

Many thanks JIM,

but it is not what I need ;)

for time offset i use .TimeZoneOffset which work very well,

if you have time, please see my code

have a great day

my purpose is to compare 2 different date and display the time between them

Take two moments and get a duration?

Moment - Moment      Moment.subtract()    Duration  The span between Moments

many thanks again mate, but sorry, it was not my question at all,

my question is, why with my code I have sometimes utc offset error and sometimes not

my code compare 2 dates but supposed both on utc.

the settings data picker should retourn an UNIX value?!

hi everyone !

I'm still stuck with this...

markdotai could you help me ?

have a great day

jim_m_58 over 5 years ago in reply to Shent-Aurkhan (SHN)

Are you using a date from app settings? the "date" type.

That's been odd since the day it was introduced. (years ago) Last I recall is it still didn't work right with GCM, and had different issues between iOS and Android.

I think it might work right with the Connect IQ phone app, but never checked myself.

See the description for this witch face to see some of the oddness with the date setting:

Starting with:

**** [ TROUBLESHOOTING ] ****

GCM app has bugs with regards to setting an event date.

These have been reported to Garmin. To ensure a hassle free experience, you have to abide to some rules.

hi,

yes, i use it, i have F6 and android and it works for both IQ and connect

Shent-Aurkhan (SHN) over 5 years ago in reply to jim_m_58

Hi,

The date does not seem to be the issue for me, it is the hours, odd behavior I think due to utc offset but not for everyone.
