DATE_MATCHER =

This one’s easy enough :)

/\A(\d{4})-(\d{2})-(\d{2})\Z/.freeze
TIME_MATCHER =

This unbelievable little gem is taken basically straight from the YAML spec, but made slightly more readable (to my poor eyes at least) to me: yaml.org/type/timestamp.html

/\A\d{4}-\d{1,2}-\d{1,2}(?:[Tt]|\s+)\d{1,2}:\d{2}:\d{2}(?:\.\d*)?\s*(?:Z|[-+]\d{1,2}(?::?\d{2})?)?\Z/.freeze
SECONDS_PER_DAY = 
60 * 60 * 24
MICROSECONDS_PER_SECOND = 
1000000
SEC_FRACTION_MULTIPLIER =

So this is weird. In Ruby 1.8.7, the DateTime#sec_fraction method returned fractional seconds in units of DAYS for some reason. In 1.9.2, they changed the units – much more reasonably – to seconds.

RUBY_VERSION == "1.8.7" ? (SECONDS_PER_DAY * MICROSECONDS_PER_SECOND) : MICROSECONDS_PER_SECOND
