4.2EA2 SQL History Timestamp shows as numeric value

Sentinel

    In the SQL History pane, the timestamps are displaying as numer values rather than timestamps.

     

    Typical values for some recent records include:

     

    1485965779265

    1485823379694

    1485823365042

    1485823351274

    1485823304506

    1485799310465

    1485799248052

    1485798931157

    1485798872218

     

    Not being formatted as a date makes it rather difficult to find queries run on specific days.  Is there a way to fix this and get back the usual format?

     

    Additional note: these values appear to match the timestamp elements in the history xml files:

    <timestamp><![CDATA[1485966364143]]></timestamp>

    So does this mean it's a conversion issue or something else?
