Hashing random blocks failures and hard errors

[DawBin]

I'm running a script that selects random historical blocks. For each random block I am passing the correct nonce. Sometimes the hash is correct, sometimes it is not correct and other times there is an error. Here are repeatable samples using the example code...

CORRECT HASH:

    //
    //Target Block: 0000000099e42d2610bde471f80267d6e3393f8b653a45c3cb409ae870d4cdb1
    //Correct nonce will be: 1655861781
    //

    const block = {
            version: 1
            ,previousblockhash: '000000004b163c55c375213d53647f16d89fc6918b60afeaedc5bef848f813b5'
            ,merkleroot: 'b1ea695ce6cdd3acfdd4f59d247590a857ea02d3b7f99cff12a596f0bde62d49'
            ,time: 1259804330
            ,bits: '1d00ffff'
    }
    0000000099e42d2610bde471f80267d6e3393f8b653a45c3cb409ae870d4cdb1 1655861781 <-SUCCESS

INCORRECT HASH:

    //
    //Target Block: 000000000000000000937fa8b710d4acbe9dea7eb8f252b880f37d4439ccce19
    //Correct nonce will be: 2005385666
    //

    const block = {
            version: 536870914
            ,previousblockhash: '0000000000000000011449a27a730a8d03011dcd1eaec65c1b7f1c04649cd150'

ERROR (seems to be related to nonce value):

Could you upload the code or snippet you're using to pull the random historic blocks? Going to take a crack at replicating.

[DawBin]

Certainly, here it is...

the timestamp in mined blocks is often wrong
