About Format of Clock Component

I'd like to have a saved file name like yyyymmdd, e.g. 20160417.png.

When I use pattern : yyyyMMdd, the saved file name is 2016Apr17.png.

When I use pattern : yyyymmdd, the saved file name is 20162417.png.

When I use pattern : yyyymd, the saved file name is 20163017.png. 

Why the month can't be a right number?

If you follow the (?) button from the Designer Clock component entry, it gives you a popup window with a little text, and a link to https://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html

with the full list of format items.

See attached.

Thank you so much! The link you offered is so detailed. "m" means "Minute in hour".

 I set the pattern to yyyyMMd, then the time displayed as 20160418, that's so great!

You may want to use yyyyMMdd for the format pattern instead.

yyyyMMd will give 2016046 rather than 20160406 when the day value is less than 10.
