Hi all,
I have a newbie question relating to calculations between two time values.
I want to perform a calculation between two values in a DataField:
1. The info.elapsedTime value, and
2. (The info.startTime value + 10 hours and thirty minutes).
I want to subtract #1 from #2, and then to display the result in the format hh:mm:ss.
I have been struggling with this for a while and just can't get it to work. Can somebody please help me out?
Cheers,
James.
I want to subtract #1 from #2, and then to display the result in the format hh:mm:ss.
var goalTimeSec = 10 * Cal.SECONDS_PER_HOUR + 30 * Cal.SECONDS_PER_MINUTE;
var elapsedTimeSec = info.elapsedTime / 1000;
var deltaTimeSec = 0;
if (elapsedTimeSec < goalTimeSec) {
deltaTimeSec = goalTimeSec - elapsedTimeSec;
}
var deltaTimeSec;
if (elapsedTimeSec < goalTime) {
deltaTimeSec = goalTimeSec - elapsedTimeSec;
}
else {
deltaTimeSec = elapsedTimeSec - goalTimeSec;
}
function format_duration(seconds) {
var hh = seconds / 3600;
var mm = seconds / 60 % 60;
var ss = seconds % 60;
if (hh != 0) {
return Lang.format("$1$:$2$:$3$", [
hh,
mm.format("%02d"),
ss.format("%02d")
]);
}
else {
return Lang.format("$1$:$2$", [
mm,
ss.format("%02d")
]);
}
}
Are you just trying to calculate the offset from a goal time of 10h 30m? If so, this could be more easily expressed as remainingTime = goalTime - elapsedTime.
The only remaining thing to do is to format the time delta as hours/minutes/seconds. This is typically where people run into problems.function format_duration(seconds) {
var hh = seconds / 3600;
var mm = seconds / 60 % 60;
var ss = seconds % 60;
if (hh != 0) {
return Lang.format("$1$:$2$:$3$", [
hh,
mm.format("%02d"),
ss.format("%02d")
]);
}
else {
return Lang.format("$1$:$2$", [
mm,
ss.format("%02d")
]);
}
}
