  4. comment changed to:
    It looks like clock free scan recognizes literal "T" in (undocumented?) ISO 8601 timestamp incorrectly, I guess as a legacy (military?) timezone "T".

    % clock format [clock scan "2020-05-20 14:40:00  T"    ] -gmt 1
    Wed May 20 <b style="color:red">21:40:00</b> GMT 2020
    </pre>
    This seems not correct in my opinion (despite the documentation says about literal "T" by ISO without "-" separator in date only, recognize "T" as timezone looks weird to me). 
    
    I think either we must aggressively strict the timezones bison/yacc rules (must consider word boundaries or something similar) or ISO format must be extended with YYYY-MM-DD date.
