MATLAB: Display date data on x-axis

plotserial date number

I have a date data (dd.mm.yyyy HH:MM). After importing, the date data change into serial-date-numbers (729756). I use this type of data to plot. However, the type of data displaying at x-axis is serial-date-numbers type. Now I want my x-axis display as (dd.mm.yyyy HH:MM). I need your help. Thank you very much in advance

The easiest approach is likely to use the datetick (link) function.

MATLAB: Convert Datetime to UTC

Try this:

T = datetime('now', 'Format','yyyy MM dd HH mm ss', 'TimeZone','local')   % Local Time Zone
T.TimeZone = 'Z'                                                          % Convert To UTC

producing:

T = 
  datetime
   2020 06 23 18 19 09
T = 
  datetime
   2020 06 24 00 19 09
