Implement timestamp in InstructionCode and change TIME to DATE, also add TIME as time

In "crates/datex-core/src/global/instruction_codes.rs" line 235 there is `TIME, // ~2022-10-10~`, this is DATE `year-month-day`.
So Time has to be `hour-min-sec-ms(optional)`, also add Unix timestamp in ms since `January 1, 1970, 00:00:00 UTC`, same as in js/rust
