How to readjust a timestamp?

Hi all,

I am trying to read some data collected. I made a mistake and inputted 07/24/2023 instead of 07/23/2023. Now the matlab date which is in a number format is unable to correctiy read the data based on these timestamps.

Please, I will apprciate it if any one can help me adjust the matlab date 07/23/2023 to 07/24/2023 or any suggestions will be appreciated.

NOTE: the malab date is in a number format eg. 7.390905000610648e+05

"the malab date is in a number format eg. 7.390905000610648e+05"

The number format is the number of days since Jan 0, 0000 (see: datenum), e.g.:

datenum('07/23/2023')

ans = 739090

datenum('07/24/2023')

ans = 739091

"help me adjust the matlab date 07/23/2023 to 07/24/2023"

In order to adjust the date forward by one day (e.g., from 07/23/2023 to 07/24/2023), you can add 1 to the number.

num = 739090.5000610648;
datetime(num,'ConvertFrom','datenum')

ans = datetime
   23-Jul-2023 12:00:05

num = num+1;
datetime(num,'ConvertFrom','datenum')

ans = datetime
   24-Jul-2023 12:00:05

(If you want to go from 07/24/2023 to 07/23/2023, you would subtract 1. Your question says you want to do both.)
