Blockchain.info unconfirmed transactions

[theGECK]

I currently have several unconfirmed transactions in my blockchain.info wallet

https://blockchain.info/tx/c5d7fce24d811cec2221d318e6be876ea475374cc8806b3e7e137b096ee51fed
https://blockchain.info/tx/4b3a32a66e5c279c1747ce1464b5b9a0ced0b9b57b54e268cf4a322c4e1ca427
https://blockchain.info/tx/751d7f06e286c5326fd5f1c93855f1dc914ac7f0eb847381f67d8bb1b1b59cad

I'm wondering if anybody knows what to do about them. Another thing that bothers me about them is that the timestamp in those tx pages is different than the timestamp being shown to me on my "My Transactions" page. In PC clients I could tell it to recheck the blockchain, but I don't have that option in blockchain.info.
