Posted on by JBille 43

I'm making a flow where I need a time in Epoc time, but I can't figure out how to make an expression that do this.

As a work around I made it in my data set from SQL view where I added a column DATEDIFF(s, '1970-01-01 00:00:00', GETUTCDATE()) as Epoch.

But I can't find a flow expression in flow that do the same as SQL's datediff.

    @JBille

    Flow does not have a datediff expression - you'll want to use the ticks expression to convert date/times and then do some math.

    Here is a link to a post with a similar issue to get you started.

    Hi @JBille,

     

    Just like the method from @ScottShearer provided, the ticks() function can return the ticks property value from 0001-01-01T00:00:00Z to a specified timestamp. A tick is a 100-nanosecond interval, one second is 10,000,000 ticks. So you can Calculate the difference between utcNow and 1970, then div it to get the seconds.

    you can use the following expression:

    div(sub(ticks(utcNow()),ticks('1970-01-01T00:00:00Z')),10000000)
