I am trying to create a timelock transaction, but I am unable to use a UNIX timestamp on testnet. However, if I use a block height the transaction works.
When I use a block height that is in the future and broadcast the transaction, I get:
sendrawtransaction RPC error: {"code":-26,"message":"non-final"}
When the block height is reached, the transaction goes through as expected.
When I make the locktime above 500,000,000 I get a different message:
"non-mandatory-script-verify-flag (Locktime requirement not satisfied)"
I have tried several different random timestamps from various years (2013, 2020) and I get the same error message. If I make the transaction with a large locktime like 400,000,000 I get the expected "non-final" message. It only happens when I go over the 500,000,000 minimum.
I have decoded both transactions, and the only noticable difference is the locktime.
Here is the raw transaction with the UNIX timestamp from 2013:
0200000001ab306f83a06f006f76695f0911fbe095d2443798f232e91e7a78e8bbf2050ec40000000088483045022100c381bfb9de6930ecb45cf2cc13581aca8c42e9f570615cabf1a631fbf137270b022026636856bbf250d169f7608abe1ab4fcba13c495ffa27ee4e821d38d626365ab012103803a5bbbe00dad7dbb29dd5f4d7883ac049bad52d78b456cda12591e26ae70241c00b17576a91450840658811828e04f5501bf3fe87f012d297bdd88acfeffffff01e4250000000000001976a914f005b469eb92525da0294247b5d0ae169efd78f588ac2e377452
Here is the raw transaction with block height:
0200000001ab306f83a06f006f76695f0911fbe095d2443798f232e91e7a78e8bbf2050ec40000000087473044022011704ab11cf526e656aaf681c9ab2c3002fd8a3982383afcad8ec46af68f099d022061c06671dcc7cf6e192c541b4692a809ea97711ed2866c004780054028cc5237012103803a5bbbe00dad7dbb29dd5f4d7883ac049bad52d78b456cda12591e26ae70241c00b17576a91450840658811828e04f5501bf3fe87f012d297bdd88acfeffffff01e4250000000000001976a914f005b469eb92525da0294247b5d0ae169efd78f588acfbb22400
