Issue
With Script Programs in Continuum we were able to check the variable time against an integer value. Like "if time>500 then...".
In StruxureWare Building Operation time is of the type datetime, no longer an integer.

Environment
- Script Program
Cause
In StruxureWare Building Operation a datetime internally is now a 64 bit number, so dates can go beyond the year 2038 which was the top limit for Continuum. Numbers in script for StruxureWare, like in Continuum are just floats ( 32 bits ) so when trying to map a 64 bit number ( the date ) into a float it is not going to work. You will get very erroneous readings, therefore the ban.
Resolution
Here are some examples of the correct StruxureWare program:
Remember that for the dates, you can only compare dates to dates, not dates to numbers…
In general,
you CAN do the following:
compare dates to dates ==> if Date1 > Date2 then
add numbers to dates ==> LaterDate = LastDate + 24*3600
subtract numbers from dates ==> EarlierDate = LastDate - 24*3600
you CANNOT do the following
compare dates to numbers ==> if Date1 > 500 then
