So when using block-based or time-based, the same amount of time can be encoded with the available number of bits. Converting from a sequence number to seconds is performed by multiplying by 512 = 2^9, or equivalently shifting up by 9 bits. When the relative lock-time is time-based, it is interpreted as a minimum block-time constraint over the input's age. A relative time-based lock-time of zero indicates an input which can be included in any block. More generally, a relative time-based lock-time n can be included into any block produced 512 * n seconds after the mining date of the output it is spending, or any block thereafter. -The mining date of the output is equals to the Median Time Past of the previous block which mined it. +The mining date of the output is equals to the median-time-past of the previous block which mined it. -The block produced time is either equals to median time past of its parent or to its nTime field, depending on the state of BIP113 (MTP). +The block produced time is either equals to median time past of its parent or to its nTime field, depending on the state of BIP113 median-time-past.
