wx.getBackgroundAudioManager () problem

my code js code is as follows

</button>
<view>
    {{time}}
</view>

The code above has no problem with the development tool, but I update ip6p and ip6sp time with iphone real machine preview every two seconds, that is, the onTimeUpdate event is only executed every 2s. Because to display the number of seconds the current music is played, it would be strange for users to look at it if it changes in 2s. I would like to ask members how to deal with it.
