Hi, I'm struggling to implement a custom date time format regular expression for the following format:
MM/DD/YYYY, hh:mm A
Example: 1/24/2023 11:30 AM
I tried something this, but not sure how to implement it in a regex action:
\d{2}/\d{2}/\d{4}\s+\d{2}:\d{2}\s+(AM|PM)

I also tried to do it on a task form, however could not do it on a submit rule (its used for a comment log, so it has to be on the submit rule). 

Also tried the format date action, but it returns the seconds as well as a day behind from the current date time for some odd reason

Hi @Prineel_V3 

This is doable…

Step 01: Format date to String. 

Format: YYYY-MM-DD HH🇲🇲ss 
Output: txt_CurrentDate

 

Step 02: Apply Regex to extract Date  

Input: txt_CurrentDate  (Output from Step 1)

Replace

Pattern: (\d{4})-(\d{2})-(\d{2})(.*)

Replacement: $2/$3/$1

Output: txt_FormatDate

 

Step 03: Apply Regex to extract Time  

Input: txt_CurrentDate  (Output from Step 1)

Replace

Pattern: (\d{4})-(\d{2})-(\d{2})(.*)

Replacement: $4

Output: txt_FormatTime

 

Step 04: Apply Regex to extract Hour  

Input: txt_FormatTime  (Output from Step 3)

Replace

Pattern: (\d{2}):(\d{2}):(\d{2})

Replacement: $1

Output: txt_Hours

 

Step 05: Convert txt Hours into Integer  

Input: txt_Hours  (Output from Step 4)

Output: int_Hours

 

Step 06

Check if Hours equals 00

Check if Hours equal 12

Check if Hours less than 12

BRANCH If int_Hours == 0

Step 06a: Apply Regex   

Input: txt_FormatTime  (Output from Step 3)

Replace

Pattern: (\d{2}):(\d{2}):(\d{2})

Replacement: 12:$2 AM

Output: txt_FormatTime 

Explanation: If the time is 00:00:01 or 00:30:20, we are going to format it as 12:00 AM or 12:30 AM

 

BRANCH If int_Hours == 12

Step 06b: Apply Regex   

Input: txt_FormatTime  (Output from Step 3)

Replace

Pattern: (\d{2}):(\d{2}):(\d{2})

Replacement: 12:$2 PM

Output: txt_FormatTime 

Explanation: If the time is 12:00:01 or 12:30:20, we are going to format it as 12:00 PM or 12:30 PM

 

BRANCH If int_Hours < 12

Step 06c: Apply Regex   

Input: txt_FormatTime  (Output from Step 3)

Replace

Pattern: (\d{2}):(\d{2}):(\d{2})

Replacement: int_hour:$2 AM

Output: txt_FormatTime 

Explanation: Get hours and minutes, append AM

 

BRANCH If int_Hours < 12  (The NO branch)

Additional Step → Minus 12 from int_Hours

Step 06d: Apply Regex   

Input: txt_FormatTime  (Output from Step 3)

Replace

Pattern: (\d{2}):(\d{2}):(\d{2})

Replacement: int_hour:$2 PM

Output: txt_FormatTime 

Explanation: Get hours and minutes, append PM

 

TESTING RESULT

I used a Datetime control for input instead of getting the actual Datetime from Context 

 

Hope that helps


Hi,

My reaction:

I think I will just use one of the built in formats in the convert a value action to avoid too many steps (unless it has to be in that specific format). Thanks for this solution though :)


If you haven’t voted for it already, there’s an idea out there to add more options to the Format Date to String action.

Hi @Prineel_V3 

Yes, I agree that this is not the best solution. 

 

Hopefully Nintex is able to improve upon this Date Format action
