Wow Eric that's great thank you!
I think what's missing is the ability to record time for the same task
across multiple sessions.
I've edited some of your code so that the start/stop buttons don't erase
the field, but just add the new timestamps to the end of the field. This
way the "start" and "stop" fields contain a list of *all *the times you
started and stopped the timer.
What I can't figure out is how to calculate the total elapsed time. What I
need to do is calculate the difference between the *last* timestamp in the
"start" and "stop" fields each time I press the stop button, then sum all
of these values.
Here is an edited version of your code:
\define startbutton()
<$button> start
<$set name="current-time" value=<<now YYYY0MM0DD0hh0mm0ss0XXX>> >
<$action-setfield start={{{ [{!!start}addsuffix[ ]addsuffix<current-time
>] }}}/>
<$action-setfield current-button="stop"/>
</$set>
</$button>
\end
\define stopbutton()
<$button> stop
<$set name="current-time" value=<<now YYYY0MM0DD0hh0mm0ss0XXX>> >
<$action-setfield stop={{{ [{!!stop}addsuffix[ ]addsuffix<current-time>]
}}}/>
<$action-setfield elapsed={{{ [{!!stop}subtract{!!start}] }}}/>
<$action-setfield current-button="start"/>
</$set>
</$button>
\end
\define showtable()
<$vars min={{{ [{!!elapsed}divide[60000]trunc[]] }}}>
<$vars minsec={{{ [<min>multiply[60]] }}}>
<$vars sec={{{ [{!!elapsed}divide[1000]subtract<minsec>multiply[1000]trunc[]
divide[1000]] }}}>
| started:|<$view field="start" format="date" template="[UTC]MMM DD YYYY
0hh:0mm:0ss.0XXX" />|
| stopped:| <$view field="stop" format="date" template="[UTC]MMM DD YYYY
0hh:0mm:0ss.0XXX" />|
| elapsed:|<<min>> minutes <<sec>> seconds|
</$vars>
</$vars>
</$vars>
\end
<$reveal default={{!!current-button}} type="nomatch" text="stop">
<<startbutton>>
</$reveal>
<$reveal default={{!!current-button}} type="match" text="stop">
<<stopbutton>>
</$reveal>
<<showtable>>
Any ideas how I can calculate the total elapsed time? Or maybe there is a
better overall approach?
