Parse time-like phrases into a javascript Date.
Inspired by the unix program [at] 1 which includes a 'timespec' for parsing time-like phrases into dates. This extends the original scope to include the past and various other changes. It's similar, but not exactly the same.
timespec=require('timespec');varis_now=timespec.parse('now');varis_now_last_week=timespec.parse('last week');varis_noon_today=timespec.parse('noon');varis_noon_yesterday=timespec.parse('noon yesterday');varis_12_weeks_ago=timespec.parse('last 12 weeks');varis_12_weeks_from_now=timespec.parse('next 12 weeks');varis_2_hour_from_now=timespec.parse('now - 2 hours');
