get tests to pass in *all* environments/timezones
add/rename/modify some methods; some tests still pending
fix getMsFromMidnight method; must include offset here too since we're not returning moments (only pure JS Dates) from sundial methods
remove unused method; fill in skipped tests
add explainer comments to getMsFromMidnight; add NB to README
address feedback; remove deprecated methods; standardize on offset mins from UTC and add warnings; use a common fn for applying formatting masks
further small fixes
more response to feedback (almost lost b/c of changes to diff) incl. additional requested tests
test cleanup (don't need async)
