New subject, TimeAddSub_s

Postby bowlesj3 » 14 Jan 2009

Is there a function kicking around to calculate a future or past time_s value. One that can add seconds or subtract seconds from a current time_s value. One that does not abort if the resulting time_s value is ahead of the currenttime_s. One that can put the results in any variable. One that is fast.

The reason is I am trying to get a future time_s value by offset and MC aborts when I do this.

Thanks,
John.

I figured it out. No need for help. Just a little persistence. Here is the code to accomplish it with a print statement output you can try out. I did not try it over the midnight time span. I don't need to worry about this myself.

You could wrap the (long hard to remember) commands shown in the print statement into a simpler easier to remember set of functions that clutter your EL code less.
result = TimeAdd_s(time_s,OneSecond);
result = TimeSubtract_s(time_s,OneHour);

John.

Code: Select all

   OneHour(1/24), {1 divided by the number of hours in a day}
   OneMinute(1/1440), {1 divided by the number of minutes in a day}
   OneSecond(1/86400); {1 divided by the number of seconds in a day}

Here is that simpler function which does it all (not tested over the midnight however). For speed it might be just as well to use the more complex set of commands above. Probably not much speed difference though.



Code: Select all

{A_TimeAddSub_s}
{
Result_s = A_TimeAddSub_s(Time_s, "A", 1, "S");
Result_s = A_TimeAddSub_s(Time_s, "A", 5, "M");
Result_s = A_TimeAddSub_s(Time_s, "A", 3, "H");
Result_s = A_TimeAddSub_s(Time_s, "A", 3, "H");
Result_s = A_TimeAddSub_s(Time_s, "S", 1, "H");
}

inputs:
   TimeIn(NumericSimple),
   AddSub(StringSimple),
   UnitsIn(NumericSimple),
   UnitsToAdd(StringSimple);
   
variables:
   AddSubAmt(0),
   OneHour(1/24), {1 divided by the number of hours in a day}
   OneMinute(1/1440), {1 divided by the number of minutes in a day}
   OneSecond(1/86400); {1 divided by the number of seconds in a day}
   
if AddSub = "A" then
   AddSubAmt = 1;
if AddSub = "S" then
   AddSubAmt = -1;
 
if AddSubAmt = 0 then
   A_TimeAddSub_s = 0
else
   begin
   if UnitsToAdd = "S" then
      A_TimeAddSub_s = DateTime2ELTime_s(ELTimeToDateTime_s(TimeIn) + ((UnitsIn * OneSecond) * AddSubAmt));
   if UnitsToAdd = "M" then
      A_TimeAddSub_s = DateTime2ELTime_s(ELTimeToDateTime_s(TimeIn) + ((UnitsIn * OneMinute) * AddSubAmt));
   if UnitsToAdd = "H" then
      A_TimeAddSub_s = DateTime2ELTime_s(ELTimeToDateTime_s(TimeIn) + ((UnitsIn * OneHour) * AddSubAmt));
   end;
     
   


Here is the caller test.

Code: Select all




Print( File("C:\Access\A_DateTimeLearningTests1.txt"),
        " Time_s", " " ,
       Time_s, " --- " ,

    " add 1Sec", " " ,
       A_TimeAddSub_s(Time_s,"A", 1, "S") , " " ,
 
       " add 1min", " " ,
       A_TimeAddSub_s(Time_s,"A", 1, "M") , " " ,

       " add 1hour", " " ,
        A_TimeAddSub_s(Time_s,"A", 1, "H") , " " ,
 
     " subtract 1Sec", " " ,
        A_TimeAddSub_s(Time_s,"S", 1, "S") , " " ,
 
       " subtract 1min", " " ,
        A_TimeAddSub_s(Time_s,"S", 1, "M") , " " ,
 
       " subtact 1hour", " " ,
       A_TimeAddSub_s(Time_s,"S", 1, "H") , " " ,
 
                  " ");



Result is the same.

I just ran another test with units of 3 instead of 1 (see below) and it does work.

Code: Select all


Print( File("C:\Access\A_DateTimeLearningTests1.txt"),
        " Time_s", " " ,
       Time_s, " --- " ,

    " add 1Sec", " " ,
       A_TimeAddSub_s(Time_s,"A", 3, "S") , " " ,
 
       " add 1min", " " ,
       A_TimeAddSub_s(Time_s,"A", 3, "M") , " " ,

       " add 1hour", " " ,
        A_TimeAddSub_s(Time_s,"A", 3, "H") , " " ,
 
     " subtract 1Sec", " " ,
        A_TimeAddSub_s(Time_s,"S", 3, "S") , " " ,
 
       " subtract 1min", " " ,
        A_TimeAddSub_s(Time_s,"S", 3, "M") , " " ,
 
       " subtact 1hour", " " ,
       A_TimeAddSub_s(Time_s,"S", 3, "H") , " " ,
 
                  " ");

It appears to work over the midnight as well. I cleaned up the test code and included it below with the results. My checks were not all that thorough so if you are using this you should do your own checks.





Code: Select all

inputs: Units(3);

Print( File("C:\Access\A_DateTimeLearningTests1.txt"),
        " Time_s", " " ,
       Time_s, " --- " ,

    " add ", NumToStr(units,0), " Sec", " " ,
       A_TimeAddSub_s(Time_s,"A", units, "S") , " -" ,
 
       " add ", NumToStr(units,0), " min", " " ,
       A_TimeAddSub_s(Time_s,"A", units, "M") , " -" ,

       " add ", NumToStr(units,0), " hour", " " ,
        A_TimeAddSub_s(Time_s,"A", units, "H") , " -" ,
 
     " sub ", NumToStr(units,0), " Sec", " " ,
        A_TimeAddSub_s(Time_s,"S", units, "S") , " -" ,
 
       " sub ", NumToStr(units,0), " min", " " ,
