Is 1545711033395 the timestamp value? What is 0000000000? Are you expecting the value you wrote to translate to 2018-12-25 04:10:33?
If you just need to convert the first values from timestamp to datetime, then this code should work.
Code:
node:Static_Data
bretype:core::Static Data
editor:sortkey=5cacc4fb6bd556f6
output:@40fe6c55598828e5/=
prop:StaticData=<<EOX
TimeStampValue
"1545711033395,0000000000"
EOX
editor:XY=180,190
end:Static_Data

prop:Script=<<EOX
splitTime = 'TimeStampValue'.split(",")
dateVal = long(splitTime[0])
#timeVal = long(splitTime[1])
emit timestamp(dateVal) as "DateValue"
