 * The first bit is unused sign bit.
 * The second part consists of a 41-bit timestamp (milliseconds) whose value is the offset of the current time relative to a certain time.
-* The 10 bits machineID, and max value is 2^10 -1 = 1023.
+* The 10 bits machineID(5 bit workid + 5 bit datacenter id), max value is 2^10 -1 = 1023.
 * The last part consists of 12 bits, its means the length of the serial number generated per millisecond per working node, a maximum of 2^12 -1 = 4095 IDs can be generated in the same millisecond.
 * The binary length of 41 bits is at most 2^41 -1 millisecond = 69 years. So the snowflake algorithm can be used for up to 69 years, In order to maximize the use of the algorithm, you should specify a start time for it.
