Security and Privacy deadlines countdown

Based on ai-deadlines by @abshkdz

Adding/updating a conference

• Read the data format description below. Note that the timezone format sign is inverted (e.g., UTC+7 is written as Etc/GMT-7). It's not a bug. I hate this format too. I'd be happy to move to a different timezone JavaScript library that uses a friendlier format, but I don't have time for that.
• Update _data/conferences.yml. You can do that on Github or locally after forking the repo.

Deadline format

The deadline field can contain:

1. The simplest option: a date and time in ISO format. Example: ["2017-08-19 23:59"] (Note that you need to wrap even a single deadline in a list).
2. If a deadline is rolling, you can use a template date, just substitute the year with %y and the year before the conference with %Y. Example: ["%y-01-15 23:59"] means there is a deadline on the 15th January in the same year as the conference.
3. A list of (1) or (2). Example of two rolling deadlines, with one in the end of October in the year prior to the conference year, and the second in the end of February in the same year as the conference:

- "%Y-10-31 23:59"
- "%y-02-28 23:59"

On the page, all deadlines are displayed in viewer's local time (that's a feature).

Note: If the deadline hour is {h}:00, it will be automatically translated into {h-1}:59:59 to avoid pain and confusion when it happens to be midnight in local time.

Timezones

The timezone is specified in tz format. Unlike abbreviations (e.g. EST), these are un-ambiguous. Here are tz codes for some common timezones:

Common name	tz
UTC	Etc/UTC
America Pacific Time	America/Los_Angeles
Pacific Standard Time (UTC-8)	Etc/GMT+8 (Yes, the sign is inverted for some weird reason)
America Eastern Time	America/New_York
Eastern Standard Time (UTC-5)	Etc/GMT+5
American Samoa Time (UTC-11)	Pacific/Samoa or Etc/GMT+11. This timezone does not use DST.
Aleutian Islands	America/Adak
