Time Stamps

The formula is brutal, but here is a gift.  it will be a formula numeric field type.

The formula uses fields called [Status Start] and [Status End] which are date/time field types. 



var timeofday DayStartTime = ToTimeOfDay("8:30 am");
var timeofday DayEndTime = ToTimeOfDay("5:00 pm");

var DateTime StartDateTime = Max([Status Start], ToTimestamp(ToDate([Status Start]), $DayStartTime));
 
var DateTime EndDateTimeTesting = If(IsNull([Status End]), Now() ,[Status End]);

var DateTime EndDateTime = Min($EndDateTimeTesting, ToTimestamp(ToDate($EndDateTimeTesting), $DayEndTime));

var Number WeekDayDays = WeekdaySub(ToDate($EndDateTime), ToDate($StartDateTime)) + 1; //(we count each day as a full workday) 

var number HoursBeforeStartEndAdjustment  = $WeekDayDays * ToHours($DayEndTime - $DayStartTime);

var datetime StartDateTimeBounded = 
  If(ToTimeOfDay($StartDateTime) < $DayStartTime, ToTimestamp(ToDate($StartDateTime), $DayStartTime), $StartDateTime);

var datetime EndDateTimeBounded = 
If(ToTimeOfDay($EndDateTime) > $DayEndTime, ToTimestamp(ToDate($EndDateTime), $DayEndTime), $EndDateTime);

Max(0,
Round($HoursBeforeStartEndAdjustment 
- Max(0,ToHours(ToTimeOfDay($StartDateTimeBounded) - $DayStartTime)) 
- Max(0,ToHours($DayEndTime - ToTimeOfDay($EndDateTimeBounded))),0.1))

Awesome, thanks. Unsure where to put formula numeric field though...This is my layout thus far

Just create a new field called [Duration Hours Worked] and put it on the form.

Gotcha. One thing please...Max(0, of the formula has an error of "Expecting duration but finding number". Should it be Max(0,ToHours.......,0.1))  ?

please post the complete formula and the complete error.

Sorry about that...This is the end of your formula

Max(0,
Round($HoursBeforeStartEndAdjustment 
- Max(0,ToHours(ToTimeOfDay($StartDateTimeBounded) - $DayStartTime)) 
- Max(0,ToHours($DayEndTime - ToTimeOfDay($EndDateTimeBounded))),0.1))

Max(0, is highlighted in yellow and when I hover over it states "Expecting duration but finding number".

It does not keep me from saving the field but I wasn't sure if it would stop the formula from working properly.

The formula editor often produces false warnings.  If the formula saves then there is no error.

I see. Thank you for your time.
