My system has python from MSYS2 integrated with my windows environment, so I can't test if Windows exhibits the same issue; however, this works perfectly in Ubuntu. The issue is %-d, %-I don't work as expected and instead cause the function call to return an empty string. 

Steps to reproduce:
import datetime
now =

Can you tell us what the expected behavior is?

From the strftime docs: "The full set of format codes supported varies across platforms, because Python calls the platform C library’s strftime() function, and platform variations are common. To see the full set of format codes supported on your platform, consult the strftime(3) documentation."

You're probably just seeing platform-specific behavior.

On cygwin, I get an empty string.
