Using eval on a token from a time picker and adding it to a label

In my Splunk Dashboard I have a time picker and charts which shows a search for each subsequent day from the earliest time selected in the time picker. I want to display a formatted date in a label for each chart. So for example: Day 1 - 15/12/2015 Day 2 - 16/12/2015 Day 3 - 17/12/2015 etc I understand that these dates can be derived from the time picker's token. Here is what I have attempted so far just for the first date but it does not seem to work: TimePicker for SourceType-15mnowstrptime($InputTime.earliest$, "%m/%d/%Y") Could anybody tell me what I am doing wrong? Thanks
