Why does issue import divide time values by 60?

Question

On JIRA v7.12.1, when I import an issue with "28800" in the "Original Estimate" field, I expect the issue to have an original time estimate of one eight-hour day (ie 28800 seconds).  However instead it has a value of eight minutes! ("8m")

When I multiply the time value by 60 and re-import, the original time estimate is 1d.

Why is the import function dividing the 'seconds' time import by 60?

I'm having the exact same issue while importing.

If you try to do the import using the above data, does it also do the divide?
