Please help...ADF...I need to subract one day to this value

Question

Hi @Nasreen Akter @KranthiPakala-MSFT @MartinJaffer-MSFT @MarkKromer-MSFT

I have the following in a web activity in ADF

   "DisplayName": "",  
    "FirstName":  "@{item().FirstName}",  
    "LastName": "@{item().LastName}",  
    "MiddleName": "@{item().MiddleInitial}",  
    "LastModifiedTimestamp": "**@{item().timestamp}**",  

AND I need to subtract one day in the @{item().timestamp} (STRING). How can I do this? I have tried many things...

Thanks!
Mike

You can use addDays function
