Here is what "The Single UNIX Specification, Version 2" that I
downloaded about a year ago says:
Implementations may place limitations on the maximum timeout
interval supported. On all implementations, the maximum timeout
interval supported will be at least 31 days. If the timeout
argument specifies a timeout interval greater than the
implementation-dependent maximum value, the maximum value will be
used as the actual timeout value. Implementations may also place
limitations on the granularity of timeout intervals. If the
requested timeout interval requires a finer granularity than the
implementation supports, the actual timeout interval will be
rounded up to the next supported value.
So it looks the implimentation doesn't agree with this, and the
man page should probably say what the max timeout is.
(Excerpt is from http://www.opennc.org/onlinepubs/7908799/xsh/select.html).
