In order to enable an iCal export link, your account needs to have an API key created. This key enables other applications to access data from within Indico even when you are neither using nor logged into the Indico system yourself with the link provided. Once created, you can manage your key at any time by going to 'My Profile' and looking under the tab entitled 'HTTP API'. Further information about HTTP API keys can be found in the Indico documentation.
Additionally to having an API key associated with your account, exporting private event information requires the usage of a persistent signature. This enables API URLs which do not expire after a few minutes so while the setting is active, anyone in possession of the link provided can access the information. Due to this, it is extremely important that you keep these links private and for your use only. If you think someone else may have acquired access to a link using this key in the future, you must immediately create a new key pair on the 'My Profile' page under the 'HTTP API' and update the iCalendar links afterwards.

Time from classical relativistic physics toward quantum gravity
(Max Planck Institute for Gravitational Physics (Albert Einstein Institute))
Via Enrico Fermi, 40
00044 Frascati (Roma)
I survey briefly the main lessons about the nature of physical time from (special and general) relativistic physics. They amount to a progressive dismissal of common sensical assumptions about time and a difficult learning process about what are its real physical features. I then outline how the search for quantum theory of gravity and spacetime is challenging even more our understanding of the spatiotemporal aspects of the world, and suggests a more radical, complete disappearance of time (and space) from the fundamental structure of the universe. The conceptual challenges of this radical disappearance of time will be emphasised, alongside the physical ones.
