ArgumentError: year too big to marshal
I encountered the problem, that marshaling a Time object does not always work.
Try run following commands in irb that will raise an error:
Marshal.dump(Time.new(1900)) #Traceback (most recent call last): # 3: from (irb):35 # 2: from (irb):35:in `dump' # 1: from (irb):35:in `_dump' #ArgumentError (year too big to marshal: 1899 UTC) Marshal.dump(Time.new(1899)) #Traceback (most recent call last): # 3: from (irb):37 # 2: from (irb):37:in `dump' # 1: from (irb):37:in `_dump' #ArgumentError (year too big to marshal: 1898 UTC)
Following commands will work fine:
Marshal.dump(Time.new(1901)) # => "\x04\bIu:\tTime\r\xF7/\x00\x80\x00\x00\x00\x00\a:\voffseti\x02\x10\x0E:\tzoneI\"\bCET\x06:\x06EF" Marshal.dump(Date.new(1899)) # => "\x04\bU:\tDate[\vi\x00i\x03@\xD8$i\x00i\x00i\x00f\f2299161"
I'm in timezone CEST (UTC+2).
I tested it at MacOS High Sierra (10.13.6 (17G65)) and Ubuntu 16.04.5 LTS (GNU/Linux 4.4.0-135-generic x86_64) with two Ruby versions:
- ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-darwin17]
- ruby 2.6.0preview2 (2018-05-31 trunk 63539) [x86_64-darwin17]
I expect that all Time objects can be marshaled, even if they are prior 1900.

This is a limit of current marshal format of
Time, not a bug.
This is a patch to extend the limit, but it has a little problem on marshal data compatibility.

Time with this patch will be loaded as the distant future, when loaded in old ruby.
