The new format will read similar to HT[year][month][day]. I presume that they wish to be this precise for warranty purposes. The month format shall be between 1 - 12, but the day format will take a slightly different shape. Days will go from 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F, G, H, J, K, L, M, N, P, R, S, T, V, W, X, Y, Z. Day Z represents day 31.

Just be sure you wrap it in an exception handler because not all devices have this file.

At least the following devices are known to have this file world-readable: • Galaxy Nexus • Nexus S • Motorola Xoom 3g • Toshiba AT300 • HTC One V • Mini MK802 • Samsung Galaxy S II You can also see my blog post here: where I discuss what other files are available for info.
