Powershell's Get-date: How to get Yesterday at 22:00 in a variable?

Question

For a check i need yesterday\'s date at 10:00pm in a variable.

I get yesterdays Date and current Time with

$a = (get-date).AddDays(-1)

Answer 1

I see this topic, but in my case I was looking for a way to improve the format. Using UFormat and adding -1 day

(get-date (get-date).addDays(-1) -UFormat "%Y%m%d-%H%M")
