I imagine the reason you want to do it without the view widget is because
it does not accept a variable as an input?, only tiddlers and fields.
Something I have tried to get fixed because its out only built in date
converter.
- I have one possible solution which needs me to spit the longer
timestamp into separate characters but the split[] operator does not do
this.
- Here is another approach using maths operators, buit needs a little
reworking for your own use.
\define timeonly(timestamp)
<$list filter="[[$timestamp$]length[]]" variable=length>
<$list filter="[<length>match[5]]" variable=nul>
$timestamp$<br>
</$list>
<$list filter="[<length>match[17]]" variable=nul>
{{{ [[$timestamp$]remainder[100000000]divide[1000000]trunc[]]
}}}:{{{ [[$timestamp$]remainder[1000000]divide[10000]trunc[]] }}}<br>
</$list>
</$list>
\end
<$list filter="20200520223405903 23:45 22:21" variable=timestamp>
<$macrocall $name=timeonly timestamp=<<timestamp>>/>
</$list>
Regards
Tony
