:global setssidwithdate do={
/system clock
:local vdate [get date]
:local vdoff [:toarray "0,4,5,7,8,10"]
:local MM [:pick $vdate ($vdoff->2) ($vdoff->3)]
:local M [:tonum $MM]
:if ($vdate ~ ".../../....") do={
:set vdoff [:toarray "7,11,1,3,4,6"]
:set M ([:find "xxanebarprayunulugepctovecANEBARPRAYUNULUGEPCTOVEC" [:pick $vdate ($vdoff->2) ($vdoff->3)] -1] / 2)
:if ($M>12) do={:set M ($M - 12)}
:set MM [:pick (100 + $M) 1 3]
}
:local yyyy [:pick $vdate ($vdoff->0) ($vdoff->1)]
:local dd [:pick $vdate ($vdoff->4) ($vdoff->5)]
