Description: Remove '~'.time() from internal font IDs
Adding '~'.time() is not necessary because the identifiers already include
the result of the pdfkey() function, which gives increasing numbers through
a process lifetime.
.
Keeping '~'.time() only makes the output unreproducible and adds a slight
performance penalty for thesyscall needed to get the current time.
