I have a csv file with some columns, like date and time. The date is a 10 digit format, unix format from what i read online. examples are: 1567285228,1567285348, 1567371053.I found that I can use the formula: =(((A2/60)/60)/24)+DATE(1970,1,1) to calculate the proper date from the code, but the problem is that my csv is for one entire month, the codes are different, but the proper date gives me only 2 values: 01 sept 2019 and 31 aug 2019. How can I find the REAL dates, for the WHOLE month?
Also, the time when the measurements are taken are for example: 712980, 713040 ,713100,713160, but when i use excel to format the time stamp to proper time, it only shows me 12 AM. How can I calculate the proper dates and time, so that I can analyse the data from the csv?
