How to Work

The time scripts include two parts: time index state type script and time info type script.

The time index state cell data has two bytes: index(uint8) and sum_of_time_info_cells(uint8). Every time the time index state cell is updated, the index will increase by one and the index is always guaranteed to be between 0 and sum_of_time_info_cells(not include sum_of_time_info_cells).

sum_of_time_info_cells is equal to 12, which means there are 12 time info cells

The time info cell data has two parts: index(uint8) and timestamp(uint32) or block number(u64), so the length of the time info cell data will be five or nine. The timestamp or block number corresponding to the index of the time index state cell is currently the latest.

For example:

0x06604884b8          // the time info cell data with index and timestamp

0x050000000000145030  // the time info cell data with index and block number

The timestamp and block number are big endian.
