silence in front of generated audio mpegts

Let a.ts be an mpegts with aac encoded audio only.
/ffmpeg/ffmpeg -i a.ts -acodec aac -strict -2 -loglevel debug audio.ts
if I convert a.ts and audio.ts into .wav I will get two wav files, one of them has silence in front of it. I used audacity to determine that about 0.031s audio.ts will have some silence.
I can see that a.ts has 215 audio frames and audio.ts 216.
Any explanations why is silence added to ts? As far as I can see it could be a bug.
Summary: the command at top introduces one extra frame to the start of aac stream, making aac longer as it should.
