MATLAB: How to convert time in nanosecond to numeric value in order to be able to compare these timeseries

Question

Hello,

I have the number of *.csv files that are same structure (same column number), but row numbers are different. I use readtable to upload data to matlab. I need to compare timeseries of different csv files. The example of timeseries:

'08:34:37.762296992'

'08:34:37.762450580'

'08:34:37.762450580'

'08:34:37.762460422'

'08:34:37.762460422'

'08:34:37.762472108'

'08:34:37.762472108'

'08:34:37.762543205'

'08:34:37.762543205'

'08:34:37.762673812'

How to convert this type to timeseries to numeric value in order to be able to compare them?
