Calculate DateTime with results in same DateTime format

[ultrAslan]

Hello!

for my flow I need the difference of two Outlook calendar timestamps to add/subtract to another timestamp. The results then in the same time format.

To calculate the time difference I use

div(div(mul(sub(outputs('CalendarItemA'),outputs('CalendarItemB')),100),1000000000),60)

This gives me the time difference in minutes.
How can I now subtract this from a CalendarItemC or add to that?

Could it be possible to fulfill the requirements by calculating this way:

addToTime('1000-12-30T00:00:00Z',outputs('Difference),'Minutes','yyyy-MM-ddTHH:mm:ssZ') 

while Difference is the result of the sub-action above.

Thank you for any help!

Hey @ultrAslan 

you can use

addMinutes function for this.

Default expression:

addMinutes(timestamp, minute to add or subtract, optional: format date time)

For adding minutes use:

addMinutes(outputs('CalendarItemC'),outputs('TimeDiff'))

For Subtracting just use a negative sign in the above expression:

addMinutes(outputs('CalendarItemC'),-outputs('TimeDiff'))
