Question

I’m trying to get a double value with seconds to convert to a custom time format. I’ve tried SimpleDate Format but that doesn’t work…

I have a double value in this format: 407.33386569554585 (representing 407 seconds and 333 milliseconds …).

I need that in this format: HH/MM/SS.MS

How would i do that?

Thanks in advance!

Multiply by 1,000 then cast to a long and construct a Date with it.

Date date = new Date((long)(dubTime*1000));

From here, you can use a SimpleDateFormat to make the string you’d like.

String formattedDate = new SimpleDateFormat("HH/mm/ss.SSS").format(date);
