Thanks for suggesting that. I installed the attached patch to Emacs master to 
implement something along the lines you suggested. I am cc'ing Ashish Shukla who 
reported Bug#19874 ("25.0.50; encode-time not working as expected"), as well as 
Wolfgang Jenkner who helped debug that, to give them a heads-up that the fix for 
Bug#19874 has changed.
