When Tails starts, the system time zone is set to GMT (Greenwich Mean Time). This time zone might be a few hours in the future if you are west of the United Kingdom, or in the past if you are east of the UK. The minutes should be accurate.
If connecting to Tor using a bridge fails and you have to [[set the clock and time zone|doc/anonymous_internet/tor/troubleshoot]] of your computer, the time is displayed in your time zone instead of in GMT.
<p>Fixing the clock when Tails fails to connect to Tor is currently the only way of changing the time zone of the time displayed in the top navigation bar.</p>
<p>In the future, we want to make it possible to change this time zone ([[!tails_ticket 10819]]) from the desktop and store it in the Persistent Storage ([[!tails_ticket 12094]]).</p>
Even if the time is displayed in your local time zone in the top navigation bar, the internal time used by all applications in Tails is still in GMT to protect your anonymity.
For example, the sending time of emails in *Thunderbird* or messages in *Pidgin* is always in GMT to avoid leaking your time zone to the people you write to.
