Flow - Calculate Date Diference

Definition :- ticks(timestamp: string) - Returns the number of ticks (100 nanoseconds interval) since 1 Jan 1601  00:00:00 UT

 

Scenario :-

 

SharePoint list contains following columns:-

 

Title (Single Line of Text)

Contract Executed Date (Date)

 

Capture.PNG

 

 MS Flow :-

 

Get items from list

Run Select data operation to calculate number of days between Today's date and the Contract Executed Date

 

 

Capture.PNG

 

 

 

 

 

 

 

 

 

The expression for Days Since Contract Executed :-

div(sub(ticks(formatDateTime(utcNow(),'yyyy-MM-dd')),ticks(item()?['ContractExecutedDate'])),864000000000)
 
ticks(formatDateTime(utcNow(),'yyyy-MM-dd') - Number of Ticks since 1 Jan 1601 and Today's Date
ticks(item()?['ContractExecutedDate']) - Number of Ticks since 1 Jan 1601 and Contract Executed date
sub - subtracting the number of ticks
div - divide the result from 864000000000 (conversion from nanoseconds to days)
 
Output of Select when Flow runs :-

Another use case would be to do date comparisons using Ticks
 
Filter all contracts which have Contract executed date in the last week
 
Capture.PNG
 
ticks(item()?['ContractExecutedDate']) - Number of Ticks since 1 Jan 1601 and Contract Executed date
ticks(formatDateTime(adddays( utcNow(),-7),'yyyy-MM-dd')) - Number of Ticks since 1 Jan 1601 and [Today's Date - 7 ] (in the last week)
 
utcNow() - current date and time
adddays( utcNow(),-7) - adds (-7) days to todays date 
formatDateTime(adddays( utcNow(),-7),'yyyy-MM-dd') - format the date time to date 'yyyy-MM-dd'
 
Check if ticks - Contract Executed date is greater than the ticks  - since Last week
 
Data in Contracts List :-

Hi Mdorrani,

 

Maybe you can help me with this:

https://powerusers.microsoft.com/t5/Building-Flows/Copy-item-from-sharepoint-list-if-item-is-created...

 

I build the "Select" part of the flow based on this article, but i can't seem to use the output it gives me?

 

 

 

 

For me, worked this way:

 

add(mul(div(Sub(ticks(utcNow()),ticks(item()?['Estimated_x0020_Delivery_x0020_D'])),864000000000),-1),1)

 

 

 

Hi Guys,

 

I hope this helps, this is how I was able to find a solution concerning this. I defined a variable which checks how many minutes have elapsed since the record was last updated if the value is greater than 1 minute (or 5, depending on what you want), then the flow is allowed to proceed (the part that updates an item), this will stop the loop.

 

div(sub(ticks(utcNow()),ticks(triggerBody()?['Modified'])),600000000)
