From our TDS server, it is possible to export your data to an excel file.
You will see on your excel file three different ways to note the dates and times:
Timestamp: It ist the Unix timestamp hour. If you go on our website http://www.tetraedre.com/advanced/tool_timestamp.php and that you convert the number, you will obtain the date according to the GMT choosen. The advantage of this notation is that it is universal, no matter where you are in the world, you will be able to talk about the same time.
Timestamp_txt: it is about the date and time in GMT+1.
Excel date: it is about the number of days since 1/1/1900. It is then necessary to change the column format and to put it in date format. The time indicated is then in GMT+0.
