Question

I try to parse a text representation of a time into a ruby Time object.

Normally in ruby I would do it like this:

require 'time'
Time.parse('2010-12-15T13:16:45Z')
# => 2010-12-15 13:16:45 UTC

In RubyMotion I am unable to require libs and Time.parse is not available:

(main)> require 'time'
=> #<RuntimeError: #require is not supported in RubyMotion>
(main)>
(main)> Time.parse
=> #<NoMethodError: undefined method `parse' for Time:Class>

Is there a way to require the time library provided by ruby without having to copy and rewrite the whole code to make it compatible with RubyMotion?

It’s not as automatic, but you could use NSDateFormatter

date_formatter = NSDateFormatter.alloc.init
date_formatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss'Z'"
date = date_formatter.dateFromString "2010-12-15T13:16:45Z"
puts date.description
