2. The transaction has an unconfirmed parent transaction, which also has a stupid low fee of ~60 sats/byte. Until that parent confirms, this transaction will not confirm. The unconfirmed parent is: https://blockchain.info/tx/a7eeef9207d59c7dd87be0440beb638b27ebc209edf0661db5a350f7af9adcf7
3. The date changed because somebody rebroadcast the transaction, so the "relay date" got updated.
You will need to try accelerating that parent transaction (a7eeef9207d59c7dd87be0440beb638b27ebc209edf0661db5a350f7af9adcf7) using the ViaBTC TX Accelerator first. The only have 100 slots per hour, so submit it in the first minute of a new hour or you will get "submissions beyond limit" error.
Once you have accelerated that one and it gets confirmed, then work on accelerating your b00107... transaction.
thank you for your suggestion will try it now.
