Time.now has low precision
--------------------------
Key: JRUBY-1970
URL: http://jira.codehaus.org/browse/JRUBY-1970
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.1RC1
Environment: Latest JRuby 1.1RC1 from trunk
Reporter: Vladimir Sizikov
Assignee: Vladimir Sizikov
Time.now creates time instances that are too imprecise, so that subsequent
calls to Time.now might even actually return the same value:
{noformat}
10.times {
a = Time.now;
b = Time.now;
p a - b
p a.to_f - b.to_f
}
{noformat}
JRuby prints:
0.0
0.0
0.0
0.0
0.0
0.0
0.0
....
It would be great to have Time instances a bit more precise and distinguishable.
Fix is coming.
Note: This low resolution issue causes non-deterministic rubyspec failures for
Kernel#load
(since Time.now is used there for comparison).
