Look for dates anywhere in the string, to mimic normal [Time/Date].parse behavior, allowing for weekdays and dates after times
Behave even more like 1.8, where datetime strings can have any kind of characters
our more liberal regexp should not match 2000/01/01
use negative lookahead/behind in the regexp to prevent matching non-dates
ensure we only match on / as separator (1.8 behavior)
