[PATCH] tst-tzset: raise timeout to 10 seconds

[PATCH] tst-tzset: raise timeout to 10 seconds

[Alexey Brodkin]

On ARC HSDK board even though it operates @ 1GHz this test runs
~7 seconds which gives us failures all the time.

That's what happens now:
| # time .../build/timezone/tst-tzset
| Timed out: killed the child process
| Command exited with non-zero status 1
| real    0m 5.11s
| user    0m 3.59s
| sys     0m 1.45s

And that's what happens with longer time-out:
| # time .../build/timezone/tst-tzset
| real    0m 6.95s
| user    0m 4.97s
| sys     0m 1.99s
|
| # echo $?
| 0

The timeout was set to 5 in commit 
112f28e88c4ea5afbd6050e71416a23db11e4adc to increase it from a default 2 
seconds.  That was before the default timeout was changed to 20 seconds in 
commit a28605b22946c708f0a5c4f06307e1a17650ced8.  In such cases I think we 
should remove the timeout setting - explicit timeouts less than the 
default are only appropriate where there is a strong reason to want to 
*decrease* the default timeout.

There are a lot of tests that set TIMEOUT to less than 20.

We should fix all of them.

Thanks,

It's conceivable some are deliberately less than 20 (if e.g. the test 
sleeps for a certain number of seconds and does nothing else that should 
take a significant amount of time), but certainly in the absence of a 
reason for a short timeout I think such settings should be removed.
