time: add support for time64 libcs

On 32-bit low-end platforms, unnecessary promotions to 64-bit values
can be expensive, especially if division is subsequently involved
(such as during base10 formatting, etc).  We also want to avoid any
potential loss-of-precision when down-converting back in the opposite
direction.

Lastly, a 64-bit integer formats as 20 digits at most in base10.
Don't need to have any 100 byte buffers to hold that.
