Issues with Time.parse

[Jens Finnäs]

Hi,

I just started working my way around web scraping with Ruby and I just
run in to some problems with Time.parse.

I'm scraping a date from a website:

collect_last_bid =
last_bid_cell.scan(/\d{1,2}\.\d{1,2}\.\d{1,4}\b.\b\d{1,2}\:\d{1,2}:\d{1,2}/)

...which comes out nicely as "26.01.2011 21:00:08"

However, when I Time.parse the variable:

right_now = Time.parse(collect_last_bid)

...I get "Error in time.rb, Line 240 in 'parse'"

Parsing the string with Time.parse("26.01.2011 21:00:08") works fine.

Any thoughts?

run in to some problems with Time.parse.

I'm scraping a date from a website:

collect_last_bid =3D
last_bid_cell.scan(/\d{1,2}\.\d{1,2}\.\d{1,4}\b.\b\d{1,2}\:\d{1,2}:\d{1,2= }/)

...which comes out nicely as "26.01.2011 21:00:08"

However, when I Time.parse the variable:

right_now =3D Time.parse(collect_last_bid)

...I get "Error in time.rb, Line 240 in 'parse'"

Parsing the string with Time.parse("26.01.2011 21:00:08") works fine.

String#scan returns an array:

irb(main):001:0> s =3D "<td>26.01.2011 21:00:08</td>"
=3D> "<td>26.01.2011 21:00:08</td>"
irb(main):003:0> time =3D
s.scan(/\d{1,2}\.\d{1,2}\.\d{1,4}\b.\b\d{1,2}\:\d{1,2}:\d{1,2}/)
=3D> ["26.01.2011 21:00:08"]
irb(main):005:0> require 'time'

When parsing the input manually then Time.local or Time.utc are better IMHO=

Cheers guys. Runs nicely now.

Great discussion board by the way.
