I’ve got ton of spreadsheets I’m processing in PHP and one of the cells contain a timestamp which has a custom formatting of: [h]:mm:ss.0;@
This turns a number such as 2.09491E-05 into 0:00:01.8
When I read it into php I can only get the value of 2.09491E-05 but I don’t know how to convert this into seconds. Can anyone help?
In Excel, one day equates to 1. So in order to convert the Excel representation of 1.81 seconds, 2.09491E-05, into a number where each second equals 1, just multiply by the number of seconds in a day, i.e., 24*60*60, or 86,400:
