Convert seconds to HH:MM:SS.FF
44 views (last 30 days)
I have time stamps that have hh:mm:ss and nanoseconds in different columns and want to convert them to hh:mm:ss.ff.
I did as following but have no idea what to do next.
Any ideas on how can I do this?
sample.SECONDS = datenum(sample.TIME)+sample.NANOSECONDS*10^(-9);

sample.SECONDS = datenum(sample.TIME) + seconds(sample.NANOSECONDS*10^(-9));
sample.SECONDS.Format = 'hh:mm:ss.ff';
The second step will be rejected because datetime() objects have no 'ff' format specification. (And be careful, since for datetime() object, 'hh' is hour in 12 hour notation)
Perhaps you want to use datenum objects. However, datenum objects do not have a 'ff' specification either: they have a 'FF' specification.
sample.SECONDS.Format = 'HH:mm:ss.SS';
