 If bit (1 << 31) of the sequence number is not set, then the sequence number is interpreted as an encoded relative lock-time.

+The sequence number encoding is interpreted as follows:
 
 Bit (1 << 22) determines if the relative lock-time is time-based or block based: If the bit is set, the relative lock-time specifies a timespan in units of 512 seconds granularity. The timespan starts from the median-time-past of the output’s previous block, and ends at the MTP of the previous block. If the bit is not set, the relative lock-time specifies a number of blocks.
