don't use and alias?
use STRONG password.
use two factor authentication (like google Authentication)
Avoid using an alias which is short, a common english word or the same username as you use on other sites. Install the chrome extension and enter the identifier once and there should be no need to use a shortlink at all.
Also be extremely careful importing private keys or sharing private keys publicly. Cbeast
swept 45 BTC from electrum into address
https://blockchain.info/address/1MQVYyHAEE3S4iGCPUS6Kx3FYABconWBV6 using the web interface. However the private key for that address has been used as part of a bitcoin treasure hunt and the coins seem to have been automatically moved somewhere else. If you do import a private key from a treasure hunt competition or from another public source use a disposable wallet.
It appears the times are in UTC.
1.) Can you confirm that?
Yep, all times are in UTC.
The dates on clarkmoody are rendered using javascript which are automatically converted to the browsers local time settings. The dates on blockchain.info are generated server side which is much harder to localise as the users local time zone is not available to the server. I'm not sure of a good solution to this.
What kind of problem happens that stops sending such email ?
Emails have to be sent through a proxy to hide the SMTP server ip, sometimes that proxy is ddos'd or just unreliable. I would suggest to use Google authenticator instead if possible.
