Data I downloaded as a csv file has the information in a time stamp format
[TABLE="width: 192"]
<colgroup><col width="64" style="width: 48pt;" span="3">
<tbody>[TR]
[TD="width: 64, bgcolor: transparent"]ON-DUTY[/TD]
[TD="width: 64, bgcolor: transparent"]DRIVING[/TD]
[TD="width: 64, bgcolor: transparent"]TOTAL[/TD]
[/TR]
[TR]
[TD="class: xl65, bgcolor: transparent, align: right"]2:48[/TD]
[TD="class: xl65, bgcolor: transparent, align: right"]9:40[/TD]
[TD="class: xl65, bgcolor: transparent, align: right"]12:28[/TD]
[/TR]
</tbody>[/TABLE]
How do I covert this data to a number?
