1. Use an appropriate data type: In order to handle timestamps, you should use a data type that can store a sufficiently large time value (such as a 64-bit integer).

2. Use a clock with higher precision: To use a clock with higher precision, use a clock with microsecond, millisecond or higher precision to avoid the problem of eight-bit overflow with low time.

3. Avoid shaping operations: avoid using shaping operations (such as addition and subtraction) to process timestamps, and use a dedicated timestamp library or timestamp function library to ensure the correct processing of timestamps and time differences.
