EBCDIC has holes in the letter ranges and even when assuming an ASCII derived charsets it is naïve to think that all lower case letters are in the a-z range.....
Generate a random date between two other dates
... the later, multiply your random number (assuming it is distributed in the range [0, 1]) with that difference, and add again to the earlier one. Convert the timestamp back to date string and you have a random time in that range.

How does BLAS get such extreme performance?
...struction per cycle)
Third, your code is far from optimal:
You're using raw pointers, which means that the compiler has to assume they may alias. There are compiler-specific keywords or flags you can specify to tell the compiler that they don't alias. Alternatively, you should use other types tha...
