Formatting Options for Unit Group group_deltatime

[Karen K]

Is there a way to format a value of group_deltatime in decimal hours instead of hours, minutes, and seconds?

Something like

daylight: 9.5 hours

instead of

daylight: 9 hours, 30 minutes, and 0 seconds

[Tom Keffer]

I can't think of any way to do that using a simple format string. You'll have to do something like:

#set hours_up = $almanac.sun.visible.raw / 3600.0
<p>Sun up:  $("%.2f" % $hours_up)</p>

Thank you.

I sent a little PR. May you look at it?

I'm working on adding another observation to my solar monitor and I want the same thing Karen
is asking.  I didn't understand where the example code would go

I tried this is current.inc (SKIN_VERSION = 4.10.2):
    #elif $x == 'last_runtime'
      #set hours_on = $day.last_runtime.raw / 3600.0
      <tr>
        <td class="label">$obs.label[$x]</td>
        <td class="data"><p>$("%.1f" % $hours_on)</p></td>
      </tr>
and it failed miserably.

What am I missing?  The value is in seconds and coming in via mqtt.

Thx, Chris

So, after a bunch of trial-and-error and remembering various clues from other questions over time, I was able to solve this problem
in weewx/skins/Seasons/current.inc
    #elif $x == 'last_runtime'
      <tr>
        #set hours_on = $rnd(($current.last_runtime.raw / 3600.0), 1)

        <td class="label">$obs.label[$x]</td>

        <td class="data">$hours_on hrs</td>
      </tr>

solves the "I want seconds converted to hours to one decimal."
