hour() and lhour() - 10/03/16 04:13

I noticed in the manual that if BarZone is set to the local time, that hour() and lhour() are equivalent. I don't think this is the case. I think that hour() actually always refers to the UTC hour.

The following script:

Code:

function run()
{
	StartDate = 20150101;
	BarZone = ET;
	BarPeriod = 1440;
	BarOffset = 9*60;
	vars Close = series(priceClose());
	printf("\nhour: %d, lhour: %d, Close: %f", hour(), lhour(ET), Close[0]);
}

generates the following example output:

Code:

hour: 13, lhour: 9, Close: 1.109865
hour: 13, lhour: 9, Close: 1.115435
hour: 13, lhour: 9, Close: 1.116505
hour: 13, lhour: 9, Close: 1.120315
hour: 13, lhour: 9, Close: 1.119425
hour: 13, lhour: 9, Close: 1.114395
hour: 13, lhour: 9, Close: 1.108410
hour: 13, lhour: 9, Close: 1.108720
hour: 13, lhour: 9, Close: 1.107920
hour: 13, lhour: 9, Close: 1.118925
hour: 13, lhour: 9, Close: 1.118165
Chart... ok

which to me suggests that hour() is returning the UTC hour, while lhour(ET) is returning the ET hour, even though BarZone is set.

The BarZone determines when the bar starts and ends. hour() and lhour() is the UTC and local time at the end of a bar. You let a bar end at 9:00 ET. At that time lhour is always 9 and UTC is 13 or 14, dependent on daylight saving.

Thanks - that makes sense.
