技术架构与执行机制
Time Delta Mathematics
Elapsed milliseconds = End_Timestamp - Start_Timestamp. Hours = Math.floor(ms / 3600000). Minutes = Math.floor((ms % 3600000) / 60000). Decimal Hours = Hours + (Minutes / 60).
Decimal_Hours = Hours + (Minutes / 60) + (Seconds / 3600)技术限制与运行约束
- Clock-only mode assumes start and end occur within the same 24-hour cycle unless multi-day date mode is selected.

常见问题与解答
How do I convert hours and minutes to decimal hours for payroll?
Divide the minutes by 60 and add to the hours (e.g. 8 hours 30 minutes = 8 + 30/60 = 8.5 decimal hours).
Can this calculate time across midnight (e.g. 10 PM to 6 AM)?
Yes! The calculator automatically recognizes overnight shift spans.
