Question about TIMEOUT applet.

[Harald Becker]

Hi,

here is a first version of a duration helper function. As
Bernhard suggested, it always works with float (double) values,
but if required we can add a version using only integers and the
bare minimum of required suffixes (d, h, m, s).

The current version allows for the following suffixes:

  w = weeks
  d = days
  h = hours
  m = minutes
  s = seconds (default if no suffix)
  u = microseconds
  n = nanoseconds

In addition it understands fancy combined duration specifications
like:

  '1m15s'
  '1s100u'
  '1h+5m'
  '1h-5m+15s'
  '0.5m+5s'

GNU libc even allows for hexadecimal values:

   0xFFFF -> 65535 seconds


This is a first version, looking for comments.
