I adjusted the value of Time_Now to match the output for easier checking
SpoilerDays: DateTimeDiff([Time_Now],[TIMESTAMP],"day")
Hours: MOD(DateTimeDiff([Time_Now],[TIMESTAMP],"hour"),24)
Minutes: MOD(DateTimeDiff([Time_Now],[TIMESTAMP],"minute"),60)
Seconds: MOD(DateTimeDiff([Time_Now],[TIMESTAMP],"second"),60)
