sudo: memset tm when converting time attributes
strptime() which is used to parse LDAP time value does not initialize
all fields of tm structure (especially tm_isdst). This results in
random behavior - when the tm is converted into timestamp via mktime(),
the result depends on current value of tm_isdst.
