I can't get my head around how formatting a datetime variable inside a string works in PowerShell.
$startTime = Get-Date
Write-Host "The script was started $startTime"
...Do stuff...
$endTime = Get-Date
Write-Host "Done at $endTime. Time for the full run was: $( New-TimeSpan $startTime $endTime)."
gives me the US date format while I want ISO 8601.
I could use
$(Get-Date -Format u)
but I want to use $endTime to make the calculation of the timespan correct.
I have tried all permutations of $, (, ), endTime, -format, u, .ToString(...) and .ToShortDate(), but the one that works.
This question is related to

Instead of using string interpolation you could simply format the DateTime using the ToString("u")
method and concatenate that with the rest of the string:
$startTime = Get-Date
Write-Host "The script was started " + $startTime.ToString("u")
You can use the -f operator
$a = "{0:D}" -f (get-date)
$a = "{0:dddd}" -f (get-date)
