problem opening the time class

[Cris Shupp]

All,

I am trying to open the Time class to add the following method.
I am always getting this error:
NameError: uninitialized constant Time::ZoneOffset

when referencing ZoneOffset. What am I doing wrong?

class Time
def self.offset_to_zone(offset)
offset = offset.to_i
ZoneOffset.each_pair do |time_zone, zone_offset| #ERROR OCCURS
HERE!!!
return time_zone if (zone_offset == offset)
end
raise ArgumentError, "Illegal arguments! The offset " <<
offset.to_s << " is unknown."
end
end

As the error status, there is no Time::ZoneOffset constant....

Are you copying/pasting random code from somewhere?
If not, what is ZoneOffset even supposed to be?

pharrington,

Thanks for the reply.

From time.rb (the standard library)

class Time
class << Time

ZoneOffset = {
'UTC' => 0,
# ISO 8601
'Z' => 0,
# RFC 822
'UT' => 0, 'GMT' => 0,
'EST' => -5, 'EDT' => -4,
'CST' => -6, 'CDT' => -5,
'MST' => -7, 'MDT' => -6,
'PST' => -8, 'PDT' => -7,
# Following definition of military zones is original one.
# See RFC 1123 and RFC 2822 for the error in RFC 822.
'A' => +1, 'B' => +2, 'C' => +3, 'D' => +4, 'E' => +5, 'F' =>
+6,
'G' => +7, 'H' => +8, 'I' => +9, 'K' => +10, 'L' => +11, 'M' =>
+12,
'N' => -1, 'O' => -2, 'P' => -3, 'Q' => -4, 'R' => -5, 'S' =>
-6,
'T' => -7, 'U' => -8, 'V' => -9, 'W' => -10, 'X' => -11, 'Y' =>
-12,
}

I am trying to access the constant within.

Thanks,

Cris
