# Acceptable Tolerances

Windows Active Directory, AD (kerberos) ±5 min<br>
SSL/TLS/HTTPS Certificate validity window is checked. Browsers check the certificate's "Not Before" and "Not After" timestamps against your system clock (converted to UTC). example `ERR_CERT_DATE_INVALID`

### OS Corrective Behavior

When Windows detects a time update of greater than _, it will _

Registry Keys: `MaxPosPhaseCorrection` and `MaxNegPhaseCorrection` <br>
And `HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config`

≤ MaxAllowedPhaseOffset (default ~54,000s/15hrs for clients)<br>
Gradual adjustment via clock rate slewing

\> MaxAllowedPhaseOffset but ≤ 48hrs (DCs) or unlimited (clients)<br>
Logs event, may step clock or reject sample

Huge offsets (>48hrs on DCs)<br>
Rejects sample, requires manual config to accept
