Answer 1

Using PsBreakPoint:

$act= @'
$global:now = (get-date).datetime
'@
$global:sb = [scriptblock]::Create($act)
$now = Set-PSBreakpoint -Variable now -Mode Read -Action $global:sb

calling $now returns current updated datetime value

One liner:

$now = Set-PSBreakpoint -Variable now -Mode Read -Action { $global:now = (get-date).datetime }
