tools: create DateTime from Unix time

Certain parts of the code need to work
with Unix time (seconds from epoch--Jan 01, 1970).

This helper is currently intended to be used by
the crypto signing logic, but should be adopted
elsewhere to eliminate unnecessary conversions
via string and other intermediatary forms.
