Dashboard manage timepicker token on click.value, earliest not working

Hi Splunkers, I'm trying to get a dashboard timepicker to change on click to essentially zoom into the click value of a timechart + and - 60 mins. The below seems to be working just fine for the latest token, however, the earliest is doing nothing and it looks like it is reverting back to the original default on the dashboard. relative_time($click.value$,"-60m")relative_time($click.value$,"+60m") field2 is my timepicker in the above. Thanks in advance for the help,
