Nervos CKB time script including timestamp and block number

The time scripts include two parts: index state type script and info type script.
The index state cell data has two bytes: index(uint8) and sum_of_time_info_cells
(uint8). Every time the 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 info cells
The info cell data has two parts: index(uint8) and timestamp(uint32) or block number(u64), so the length of the info cell data will be five or nine. The timestamp or block number corresponding to the index of the index state cell is currently the latest.
For example:
0x06604884b8 // the info cell data with index and timestamp
0x050000000000145030 // the info cell data with index and block number
The timestamp and block number are big endian.
