Description
1) The input number of seconds (S) is converted to the time data based on standard time *1, and stored in
(D).
2) The conversion is in consideration of the leap year.
1 minute −−− 60 seconds
1 hour −−− 60 minutes
1 day −−− 24 hours
1 year (leap year) −−− 366 days
1 year (except a leap year) −−− 365 days
A leap year (4 multiple years) −−− Feb.29
3) The range which can specify the number of seconds (S) is 100 years which can be expressed by time
data.
H00000000 − HBC19137F −−− Normal conversion

Flag conditions
ΣError flag (R9007) (R9008):
− It turns on, when the specified address using the index modifier exceeds a limit.
− It turns on, when the number of seconds (S) is (S) >=HBC191380.
− It turns on, when the data memory of [D] exceeds the area.
