Dynamic Schedule - Pucks with dates prior to 2005 populate but show as "out of range"

Hello,

I can now see that the timestamp variable has been updated to allow for any dates from 1900 onwards (great stuff), however, with respect to Dynamic Schedules, anything prior to 2005 shows as “out of range” and anything prior to 1970 now does not populate on the schedule.

Thanks for your help.
