According to Google's build number naming convention, the first letter of the build is codename of the release family (which is for example K for KitKat), explains XDA. The second letter is a branch code, which allows Google to indentify the exact code branch that the build was made from (R for Release, T for Testing). The next letter and two digits indicate date code. The letter counts quarters with A being Q1 2009 and F is Q2 2010.

Based on the convention, the KTU83 Android 4.4.3 build for Nexus 5 was created on the 83rd day of Q1 2014, which is 24 March.

Sighting to a series of firmware leak, the Android 4.4.3 is expected to be rolled out soon.
