matlab serial date number to date string

The intent of this is that I will have to extract and calculate statistics on data associated with each time based on different time criteria, and I figured it would be easier if the dates were handled as numbers. N datenum (DT) converts the date string or date vector DT into a serial date number. By default, the serial day 1 corresponds to. Date numbers are serial days elapsed from some reference date.

Is there perhaps a better way to go about this? It is important that I retain the millisecond precision when it is present. The datenum function converts date strings and date vectors (defined by datevec) into serial date numbers. My work around this is as follows: for i=1:length(dates),ĭates(i)=datenum(temp,'yyyy-mm-dd HH:MM:SS.FFF')

The data is originally read from a data file, and the strings currently exist as cell arrays. There is no regular pattern as to where these strings without milliseconds occur. If you were to do the math, you’d find that. The datetime data type represents points in time, such as August 24, 2020, 10:50:30 a.m., and the duration data type represents lengths of time, such as 3 hours, 47 minutes, and 16 seconds. The problem is that not all the strings have the millisecond precision. Rather, Excel stores the value as a serial value where January 1, 1900, has a date serial value of 1 and adds 1 for every day moving forward in time. This example shows how to convert between text and data types that represent dates and times. The issue is that not every date string is the same format. They are one of two formats, ' 12:00:00.1' or ' 12:00:00' The problem is that not all the strings have the millisecond precision. I have a very long vector of date strings (1000000+) in Matlab that I want to convert to a serial number format.
