598	DosTmrQueryTime inaccuracy	dmik	David Azarewicz	"There is a test case for Firefox that demonstrates inaccuracy in intervals when using the high resolution timer (enabled by removing NSPR_OS2_NO_HIRES_TIMER=1 from the environment) located here: http://ru2.halfos.ru/core/downloads/kernel/os4/Test/timerTest.html.

The test case simply fires up a repetitive 5s timer and then logs its output. Some results are weird: you can get intervals less than 5ms and some of them are 10 times less (as low as 529 ms). This is definitely not considered as normal. With NSPR_OS2_NO_HIRES_TIMER=1 all works fine: the intervals are never less than 5000ms and the bias is not more than +40ms (pretty much expected for the low resolution timer used in this case).

There was a similar ticket #589 but it described a simply different issue (hires timer breakage after suspend). This problem has nothing to do with suspend."	enhancement	assigned	minor	Release 3.22	ACPI PSD	3.22.03
