parse
parse(date, now=self.now)
public
Parses date using Date._parse and converts it to a Time object.
If a block is given, the year described in date is converted by the block. For example:
Time.parse(...) {|y| y < 100 ? (y >= 69 ? y + 1900 : y + 2000) : y}
If the upper components of the given time are broken or missing, they are supplied with those of now. For the lower components, the minimum values (1 or 0) are assumed if broken or missing. For example:
# Suppose it is "Thu Nov 29 14:33:20 GMT 2001" now and # your timezone is GMT: Time.parse("16:30") #=> Thu Nov 29 16:30:00 GMT 2001 Time.parse("7/23") #=> Mon Jul 23 00:00:00 GMT 2001 Time.parse("Aug 31") #=> Fri Aug 31 00:00:00 GMT 2001
Since there are numerous conflicts among locally defined timezone abbreviations all over the world, this method is not made to understand all of them. For example, the abbreviation "CST" is used variously as:
-06:00 in America/Chicago, -05:00 in America/Havana, +08:00 in Asia/Harbin, +09:30 in Australia/Darwin, +10:30 in Australia/Adelaide, etc.
Based on the fact, this method only understands the timezone abbreviations described in RFC 822 and the system timezone, in the order named. (i.e. a definition in RFC 822 overrides the system timezone definition.) The system timezone is taken from Time.local(year, 1, 1).zone and Time.local(year, 7, 1).zone. If the extracted timezone abbreviation does not match any of them, it is ignored and the given time is regarded as a local time.
ArgumentError is raised if Date._parse cannot extract information from date or Time class cannot represent specified date.
This method can be used as fail-safe for other parsing methods as:
Time.rfc2822(date) rescue Time.parse(date) Time.httpdate(date) rescue Time.parse(date) Time.xmlschema(date) rescue Time.parse(date)
A failure for Time.parse should be checked, though.
