    nshlib/nsh_timcmds.c: fix incorrect time set during summer time
    
    Value zero in tm_isdst means daylight saving time (or summer
    time) is not in effect. This is obviously not true for half of the year
    in most timezones and keeping it at zero leads to incorrect time
    being set. This commit sets tm_isdst to -1, which means the information
    is not available and it should be handled according to timezone rules.
