Question about tickets import and duration format

[David CRESPIN]

Hello

I prepared a CSV file with many tickets to import into my project (JIRA 8). I have a time rounding problem after importing.
I explain: The CSV file is simple with 5 columns: summary, description, label, original time, estimated time.
According to the JIRA manual, the time format should be in seconds.
For example I have 5.52 days for a task. I convert this date into seconds (8 hours per day, 5 days * 28800 seconds, 0.52 days * 8 * 3600). 5.52 days = 158976 seconds.
After import, in this example the duration is rounded to 5.

Why have I lost the decimal values?

Thanks for your help.
