How do I isolate the 'second' component from a datetime in KDB?

Let’s say I have a KDB datetime. How do I isolate the ‘second’ part of it:

2022.02.01D14:30:12.391424612

so that would be 12?

I’ve tried t.second, but this brings back a time rather than integer.

>Solution :

You can do this:

q)`ss $ 2022.02.01D14:30:12.391424612
12i
