Hi,

Because of my poor English, I beg there would be some kind guy could  
understand me … 🙂

I’m facing a strange problem. Please check code bleow:

time = Time.local( 2008, ‘oct’, 30, 11, 25, 37 ) # Thu Oct 30  
11:25:37 +0800 2008  
File.utime Time.now, time, pathname  
File.open pathname do | f |  
print f.mtime # Thu  
Oct 30 11:25:38 +0800 2008  
end

The result would be 1sec faster than the required value. But if setted  
mtime as Time.local( 2008, ‘oct’, 30, 11, 25, 40 ), there would be no  
problem.  
It seems like the odd second value has been aligned at 2.

I have tested this problem at two different computers:

1. PC: Intel Core2 + WinXP SP3 + Ruby1.8.6 \<--------- This is  
Ok
2. Laptop: Inter Core1 + WinXP SP2 + Ruby1.8.6 \<--------- Wrong …

Could someone tell me what had happened ?

–  
Thanks,  
best regards.

FAT based file system has no capability to store the odd second  
value.
