Add LDAP Attribute (Timestamp) to ARM

I am trying to add a Computer attribute from our AD to ARM.

Its the attribute ms-Mcs-AdmPwdExpirationTime (from LAPS, LocalAdminPasswordSolution).

I Want to make this attribute visible and maybe editable, but it's a timestamp and must be recalculated to a human readable value.

Is it possible in ARM? I didn't find any documentation about possible confiuration comands.

<changeConfiguration>
  <activeDirectory>
    <PropertiesToLoad type="System.String">ms-mcs-admpwd;ms-Mcs-AdmPwdExpirationTime</PropertiesToLoad>
    <PropertiesDetails>
      <ms-mcs-admpwd>
        <AliasDisplayName type="System.String">TempAdmin</AliasDisplayName>
      </ms-mcs-admpwd>
      <ms-Mcs-AdmPwdExpirationTime>
        <AliasDisplayName type="System.String">TempAdmin Ablaufdatum</AliasDisplayName>
      </ms-Mcs-AdmPwdExpirationTime>
    </PropertiesDetails>
  </activeDirectory>
</changeConfiguration>
