DateTime beauty

I've got strings created by doing something on the order of
DateTime.now.to_s stored away.

When I'm reading them out, and showing them to the user I want to see
something pretty like:

Sat Mar 10 at 12:34pm

Heres the code I came up with:

def timeFormat( in_str )
  the_date = DateTime.parse( in_str )
  the_date = the_date.new_offset( -7.0/24.0 )
  nice_date = ''
  nice_date += case the_date.cwday
    when 1; "Mon "
    when 2; "Tue "
    when 3; "Wed "
    when 4; "Thu "
    when 5; "Fri "
    when 6; "Sat "
    when 7; "Sun "
  end
  nice_date += case the_date.month
    when 1; "Jan "
    when 2; "Feb "
    when 3; "Mar "
    when 4; "Apr "
    when 5; "May "
    when 6; "Jun "
    when 7; "Jul "
    when 8; "Aug "
    when 9; "Sep "
    when 10; "Oct "
    when 11; "Nov "
    when 12; "Dec "
  end
  nice_date += the_date.day.to_s + ' at '
  the_minute = the_date.min
  if( the_minute < 10 )
    the_minute = "0"+the_minute.to_s
  else
    the_minute = the_minute.to_s
  end
  if( the_date.hour < 12 )
    nice_date += the_date.hour.to_s + ":" + the_minute + "am"
  elsif( the_date.hour > 12 )
    nice_date += ( the_date.hour-12 ).to_s + ":" + the_minute + "pm"
  else
    nice_date += ( the_date.hour ).to_s + ":" + the_minute + "pm"
  end
  nice_date
end

It should just be a matter of using strftime:

   value.strftime("%a %b %e at %I:%M%p")

Just ignore this, then :slight_smile:

require 'date'

def time_fmt2(str)
  DateTime.parse(str).
           new_offset(-7/24.0).
           strftime('%a %b %d at %I:%M%p').
           sub(/[AP]M\z/) {|xm| xm.downcase}
end

p time_fmt2('2005/11/15 05:59') # "Mon Nov 14 at 10:59pm"
