# implemented new API calls for -lastalexa and -lastcommand
# there is now an OS-type switch that hopefully handles OSX and BSD date creation
# 2024-01-31: v0.21a trying all different date options which come to mind (first working wins)
# 2024-02-01: v0.21b changed the output of -lastalexa back to the output of devicelist.txt
# 2024-02-01: v0.21b changed the output of -lastalexa back to the output of devicelist.txt
# 2024-04-06: v0.22 changed the date calculation once again, now the date processing ignores the actual cookie validity
# and simply sets it to "now + COOKIE_LIFETIME"
