I am seeing some strange behavior with NSDate, here is my basic code in a new MacRuby project. I am running on a MacBook 2009 model, Mac OSX 10.6.6 I am using the latest XCode and the MacRuby Framework 0.7 in XCode in rbmain.rb: NSLog("In rb_main.rb") puts "NSDate = " + NSDate.date.to_s NSLog( "NSDate = " + NSDate.date.to_s) CCode.printNSDate in CCode.m: @implementation CCode + (void) printNSDate { NSLog(@"In printNSDate, NSDate = %@", NSDate.date); } @end When compiled: 64-bit Universal, the output is 2011-01-28 05:54:16.972 TestRuby[90066:a0f] In rb_main.rb NSDate = 2011-01-28 05:54:16 -0600 2011-01-28 05:54:16.976 TestRuby[90066:a0f] NSDate = 2011-01-28 05:54:16 -0600 2011-01-28 05:54:16.979 TestRuby[90066:a0f] In printNSDate, NSDate = 2011-01-28 05:54:16 -0600 When compiled: 32-bit Universal, the output is 2011-01-28 05:51:23.941 TestRuby[89998:a0f] In rb_main.rb NSDate = 2011-01-28 05:44:00 -0600 2011-01-28 05:51:23.958 TestRuby[89998:a0f] NSDate = 2011-01-28 05:44:00 -0600 2011-01-28 05:51:23.961 TestRuby[89998:a0f] In printNSDate, NSDate = 2011-01-28 05:51:23 -0600 2011-01-28 05:51:24.565 TestRuby[89998:a0f] Error loading /Library/InputManagers/Smart Crash Reports/Smart Crash Reports.bundle/Contents/MacOS/Smart Crash Reports: dlopen(/Library/InputManagers/Smart Crash Reports/Smart Crash Reports.bundle/Contents/MacOS/Smart Crash Reports, 265): no suitable image found.

For 32 bit, the Ruby code prints some time in the past that never changes. For 64 bit, the Ruby code prints the correct time. Any idea's what could be going on? Thanks!
