PowerShell: Convert String to DateTime and vise versa

Discovery

For the hundredth time I Googled how to convert String to DateTime.
It’s time I put it in my memory extension.

Description

To go from String to DateTime you need to use the class function ParseExact.
For the other direction you need to use string replacement and formatting.

Examples
