DATE_MATCHER |
= |
/\A(\d{4})-(\d{2})-(\d{2})\Z/.freeze |
|
This one‘s easy enough :)
|
TIME_MATCHER |
= |
/\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 |

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

SEC_FRACTION_MULTIPLIER |
= |
RUBY_VERSION == "1.8.7" ? (SECONDS_PER_DAY * MICROSECONDS_PER_SECOND) : MICROSECONDS_PER_SECOND |
|
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.
|
TO_TIME_AVAILABLE |
= |
DateTime.instance_methods.include?(:to_time) |
|
The DateTime class has a to_time method in Ruby 1.9+; Before that
we‘ll just need to convert DateTime to Time ourselves.
