The api im using requires a string like this:
2018-01-01T15:19:21+00:00
I can build that easy enough in codenameone, all apart from the last bit, for example +00:00, in UK right now its BST so it should be +01:00, so how would I actually produce this stirng in an automated fashion? And for some which works anywhere in the world ?
Ive written this method but as you can see that bit is hardcoded so api in uk thinks everythign is an hour off, I could hardcode it but then it will need ot change when its back to normal GMT. Im just using UK as an example, I guess the main guestion is how do you get how many hours a time is after or before GMT?
private String getIsoDateString(Date now)
{
//timePicker.setDate(now); // weird cn1 wont allow this
java.util.Calendar cal = java.util.Calendar.getInstance();
String timezone = cal.getTimeZone().getID();
cal.setTime(now);
int year = cal.get(java.util.Calendar.YEAR);
int month =cal.get(java.util.Calendar.MONTH)+1;
int day = cal.get(java.util.Calendar.DAY_OF_MONTH);
String yearS=year+"";
String monthS=month+"";
String dayS=day+"";
if (monthS.length()==1)
{
monthS="0"+monthS;
}
if (dayS.length()==1)
{
dayS="0"+dayS;
}
String hoursS = cal.get(java.util.Calendar.HOUR_OF_DAY)+"";
String minS = cal.get(java.util.Calendar.MINUTE)+"";
String secS = cal.get(java.util.Calendar.SECOND)+"";
if (hoursS.length()==1)
{
hoursS="0"+hoursS;
}
if (minS.length()==1)
{
minS="0"+minS;
}
if (secS.length()==1)
{
secS="0"+secS;
}
//year month day? or yra day month?
String dateS = yearS+"-"+monthS+"-"+dayS+"T"+hoursS+":"+minS+":"+secS+"+00:00";
return dateS;
}
