Production Downtime Tracking - Crossing the Dateline

Isaac T.

Thanks for taking the time to read this post.

I am attempting to restructure my companies end-of-shift reporting system with smartsheet to facilitate better automated data processing. An issue i am currently dealing with is how to calculate the impact or "Yield" in minutes of line downtime as we cross from one day to another. The formula i initially slapped together is...

([End HR]@row * 60 + [End MIN]@row) - (([Start HR]@row * 60) + [Start Min.]@row)

This is driven by a 24 hour time format entry system and works perfectly for what i was trying to do for 2 of our 3 shifts. 3rd shift starting at 11:00pm (2300 hrs) and ending at 7:00am (0700 hrs) creates a huge "negative" result

I dont want to implement a second date field if i dont need to as these entries are done by hourly staff while working on the shop floor, i'm trying to ensure that the entry form bloat stays to a minimum.

see image for randomly generated sample data and formula testing result.

Hi@Isaac T.

=([End HR]@row+ IF([End HR]@row < [Start HR]@row, 12, 0)) * 60 + [End Min]@row - ([Start HR]@row * 60 + [Start Min]@row)

Hi@Isaac T.

=([End HR]@row+ IF([End HR]@row < [Start HR]@row, 12, 0)) * 60 + [End Min]@row - ([Start HR]@row * 60 + [Start Min]@row)

Awesome, thanks for the quick response.

I'm not sure how i didnt come to that conclusion myself but that def. did the trick!

If you have any other challenges with time calcs, feel free to browse this thread:

I have decided to create a post that consolidates all of the different time based solutions that I have put together.<\/p>

Some of these solutions can be made more efficient or condensed into fewer but larger formulas. I am still going through these working on making them more efficient and tweaking them, but all of them have been used as working solutions.<\/p>

I thought it would be helpful to have them all in one place instead of spread out.<\/p>

I welcome all feedback, suggestions, and additions.<\/p>

I'll start by posting the published sheets to the solutions. If it is a solution to another community post, it will have a hyperlink to the original post which may help with context. Some are 12 hour clocks and others are 24 hour clocks. Some involve dates and others do not.<\/p>

I will also try to post various tips and tricks as I think of them as well such as:<\/p>

It is easier to convert the hours for 12 hour times to 24 hour times before attempting to do further calculations:<\/p>

=VALUE(LEFT([Time Column]@row, FIND(":", [Time Column]@row) - 1)) + IF(CONTAINS("p", [Time Column]@row), IF(VALUE(LEFT([Time Column]@row, FIND(":", [Time Column]@row) - 1)) <> 12, 12), IF(VALUE(LEFT([Time Column]@row, FIND(":", [Time Column]@row) - 1)) = 12, -12))<\/p>
