How to add up the time and shows up to timestamps?

[catwasicat]

Now, I have a 2 time String respectively is "Start Time" and "Usage Time"
I want to calculate both to get the "Finish Time"

Start Time + Usage Time = Finish Time

03/22/2018_11:11:06 + 00:01:03 = 03/22/2018_11:12:09

I tried to convert the both time of "Start Time" and "Usage Time" to timestamp, And add up both, After add up the both time the combine result cannot convert back timestamp.

How can i convert this result to timestamps?

Thanks!

Your "Usage Time" is a relative time, not an absolute time. So you need to use the lower case "t" in the format string.

Hi

Use the same format string as used to convert Start Time, to convert your timestamp data type back into a string.
