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

Use DateTime.Today as opposed to DateTime.Now (which is what Get-Date returns) because Today is just the date with 00:00 as the time, and now is the moment in time down to the millisecond. (from masenkablast)

> [DateTime]::Today.AddDays(-1).AddHours(22)
