Why only 28 days output in February in a leap year？

[nevergiveup]

I found there are only 28 days ouput (e.g., LST ) in February in a leap year (e.g., 2016) by clm5.0, do you konw what's wrong?
Is there any paper or website to interpret it ？

by default CESM uses a 365 day (NO_LEAP) calendar for every year so it doesn't add Feb 29th in leap years. I think you can change it to a gregorian calendar if you really want Feb 29th by using the "CALENDAR" variable in env_build.xml 6. Customizing CAM runs — camdoc documentation
