MATLAB: Time stamp formatting question

MATLABtime stamp

Hi everyone –
I have a time stamp in the following form : '0d 00:00:5.03000020980835'
I am trying to convert it into a vector in hh:mm:ss, any ideas?

Best Answer

dtstr = '0d 00:00:5.03000020980835'; 
dtstr = regexprep(dtstr,'\d+d','');         %remove days
dt = datetime(dtstr,'InputFormat','HH:mm:ss.SSS','Format','HH:mm:ss')
[update]
To preserve the number of days within the hour-count and to account for missing decimals in the seconds,
dtstr = {'0d 23:59:58.439998626709'
'0d 23:59:59'
'1d 00:00:0'
'1d 00:00:1.44000005722046'
'1d 00:00:2.44000005722046'
'1d 00:00:3.44000005722046'};
% Add .0 to time stamps that are missing the decimal
noDecIdx = ~cellfun(@(x)contains(x,'.'),dtstr); 
dtstr(noDecIdx) = cellfun(@(x)[x,'.0'],dtstr(noDecIdx),'UniformOutput',false);
% replace "d " with ":"
dtstr = strrep(dtstr,'d ',':'); 
% Convert to your desired format as durations
D = duration(dtstr,'InputFormat', 'dd:hh:mm:ss.S','Format','hh:mm:ss');
Result:
 6×1 duration array
   23:59:58
   23:59:59
   24:00:00
   24:00:01
   24:00:02
   24:00:03
