Thread: Date range exclusion filter

Here's what I came up with, but don't like the loop:

extern bool useholidayfilter=true;

I then mimicked the usetimefilter array except couldn't come up with a clever way to do the array indexes. So, I put this below the usetimefilter array.

//Holiday Filter Dates
if(useholidayfilter){
hstop[0]=D'2012.01.13';hstart[0]=D'2012.01.17'; //Martin Luther King, Jr.'s Birthday
hstop[1]=D'2012.02.17';hstart[1]=D'2012.02.21'; //Washington's Birthday
hstop[2]=D'2012.05.25';hstart[2]=D'2012.05.29'; //Memorial Day
hstop[3]=D'2012.07.01';hstart[3]=D'2012.07.07'; //Independence Day
hstop[4]=D'2012.08.31';hstart[4]=D'2012.09.04'; //Labor Day
hstop[5]=D'2012.10.05';hstart[5]=D'2012.10.09'; //Columbus Day
hstop[6]=D'2012.11.09';hstart[6]=D'2012.11.13'; //Veterans Day
hstop[7]=D'2012.11.16';hstart[7]=D'2012.11.27'; //Thanksgiving Day
hstop[8]=D'2012.12.14';hstart[8]=D'2013.12.31 23:59:59'; //Christmas
hstop[9]=D'2013.01.01';hstart[9]=D'2013.01.15'; //New Years
}

Then the following, I added to the checktime function after the gmtshift IF statement. Since I couldn't find a clever way to do the array indexes, I have to loop through each array value to see if we have a match. Therefore, the more dates you add, the slower this section becomes:

if(useholidayfilter){
int count=ArraySize(hstop);
for(int i=0; i<count; i++){
if(TimeCurrent()>hstop[i] && TimeCurrent()<hstart[i])return(true);
}
}

This seems to work ok, but maybe someone can come up with something more clean to eliminate the loop.
