Hello Julia community,

I’m trying to `loadndsparse` a csv file with a unix epoch field and turn it into a Julia `DateTime` .

What would be the correct way to do this in Julia?  
I’ve tried using the `colparsers` option but am running into difficulties how to implement the parser correctly. Basically what I want is simply map the float value of a csv column to a  
`x -> Date.unix2datetime(x)`  
but it appears to be not as simple in Julia.

Unfortunately the docs are also very _sparse_.

I’d appreciate if anybody could point me in the right direction on how to implement this correctly.

Cheers,  
Tom
