Hi Takashi,
Thank you for the report.

You are right. Guile's documentation indicates that the timeout is an
absolute time as a SRFI-18 time object, but the SRFI itself says that
timeouts are either:
* a time object represents an absolute point in time
* an exact or inexact real number represents a relative time in
seconds from the moment the primitive was called
So I guess when passed a number, that's not to be interpreted as an
absolute time from the epoch, but rather a relative timeout. We need to
update our documentation and tests, it seems, and issue a prominent NEWS
entry...
