Looks like ffmpeg can provide this feature...
Set the input time offset in seconds. [-]hh:mm:ss[.xxx] syntax is also supported. This option affects all the input files that follow it. The offset is added to the timestamps of the input files. Specifying a positive offset means that the corresponding streams are delayed by 'offset' seconds.
Too lazy to search youself?;)

You must supply an input file. Do it like this:
ffmpeg -itsoffset 3 -i hv.flv output.flv
