core: add functions to core/time.c
To support the new filter code, add helper functions that turn timestamps
into year and day-of-week to core/time.c.
Internally, these functions simply call utc_mktime() to break down the
timestamp and then extract the wanted value. This may appear inefficient,
but testing shows that modern compilers are quite effective in throwing
away the unneeded calculations. FWIW in this respect clang10 outperformed
gcc10.
