Round-trip date/time

My below expression does not match round-trip date/time:
 
addDays(body('FUTUREUSE'), -30, 'yyyy-MM-ddThh:mm:ssZ')
Lauren__0-1618837105642.pngLauren__1-1618837116001.png

 

The 'timestamp' value of the 'Wait' action 'until' inputs must be specified in UTC using the round-trip date/time pattern (for example, '2015-10-22T10:00:00Z'). For details please review the Standard Date and Time Format Strings of the .Net framework.
 
Can you please advise how I get this to function?

Hi there, so as I understood the error comes when you try to wait until the specific time?

Try to wrap the addDays function into a formattime, then it should work!

I tried it out without the formatting and I got the same issue which disappeared when formatting it.

 

formatDateTime(addDays(variables('Time'),-30),'yyyy-MM-ddThh:mm:ssZ')

Hi @Lauren_ 

 

Can you please detail a little bit further what you're trying to achieve so that I can try to help you?

 

If you're looking for more details in how to use this function I go into detail about how to use it here:

Hi Manuel, sure thing 🙂 The user selects a date that they want to look at something again (see 'FUTUREUSE' time convertor) and I am trying to set it up to remind them 30 days prior to that date. FutureUseReminder is a calculation to take the date that the user submitted and take 30 days away from it.

Hi @Lauren_ 

 

OK I think I got it but let's go step by step.

 

I did the following Flow to simulate what I think you need. I'm getting the current date/time and getting the calculation of 30 days prior.

I use the following formula:

 

addDays(variables('FUTUREUSE'),-30)

 

 

And get.

What's missing to match exactly what you need?

Hi Manuel, thanks for replying! 


I'm doing this within a condition and it won't let me set up a variable within. I've set up the variable before the condition that uses it and set a 'wait' function on the compose output, and it still fails.

but I see another problem in your approach. when the waiting time exceeds 30 days the workflow will be cancled!

so maybe you should set a column on your item (status: waiting) and let a flow check every day if the time is there to inform or do the steps 30 days before the date. 

 

I think you need to change your structure of how you solve your usecase.

Hi Kevin, your suggestion has worked! I figured if I couldn't calculate it in the Power Automate I'd have to calculate and capture it in the list 🙂
