 ### Semi-internal functions
 
-Some functions are not necessarily useful for everyday users of this library, but might be useful to someone someday. For instance, this library checks with the NTP servers automatically, so there should be no need to ever "manually" get an NTP response. But the function to do that is still exposed to the user. Even some functions that have nothing to do with time, like `urlEncode` are there for you to use, simply because they *might* be useful to someone, and the library needed them internally so they come at no extra cost in terms of size. In this manual, the names of these functions are printed in *italics* in their chapter headings, just to make it a easier for you to see which functions are core functionality and which are really not needed in everyday use.
