Subject: [PATCH] Search-ADAccount.md - TimeSpan parameter - Undocumented
 Behaviour

Previously undocumented behaviour/interaction with *ms-DS-Logon-Time-Sync-Interval*

Usage of *AccountInactive* & *TimeSpan* has the undocumented behaviour of incorporating the *ms-DS-Logon-Time-Sync-Interval*  attribute value interval [seen with the default 14 days]

Likely would've similar impacts on *DateTime* parameter - but didn't've opportunity to confirm
