Summary:                    Incorrect parsing of day range in pbx.c
Description: 
The patch
http://downloads.digium.com/pub/security/AST-2009-005-1.2.diff.txt contains
incorrect sscanf format for parsing start of day and end of day in pbx.c
whereby it assumes "day" is single digit.  That is:
  sscanf(day, "%1d", &s) should be sscanf(day, "%2d", &s) [at line 4019]
and sscanf(day, "%1d", &e) should be sscanf(day, "%2d", &e) [at line
4029]

This impact on anything that uses ast_build_timing() such as GotoIfTime()
and ExecIfTime().
