Tests: millis of 300, two bytes whose low byte is under 0x80

The check of a minimal INTEGER in the millis of an accuracy was tested only
with 128 and 999, whose low byte has its high bit set: a check that took
every two-byte value under 0x8000 for one that is not minimal left them
all passing. 300, 01 2c, is minimal and must read.
