I've added a new function that you can use in your template contents to display the amount of time elapsed since a date / time or until a date / time.
You could use this to display the amount of time a tank has been up, or how long it's been since your last water change, or when was the last time you added a coral, as an example. It can also count down toward a certain date / time, like MACNA, or a club event.
The function is called "countdown" and it takes two parameters- the first is the target date. This can be in almost any format that has both a date and optionally a time component. "January 1, 2010", "1/1/2010", "Jan 1 2:00pm", "1/1/2010 14:00:00" etc. The second parameter is related to the data format for the output, and it's a numeric value from 1 to 6. Let me give some examples for the command with different formats..
"It's been [countdown "1/1/2010" 6] since Jan 1."
would result in..
It's been 0 years, 1 months, 18 days, 8 hours, 46 minutes since Jan 1.
"It's been [countdown "1/1/2010 04:00" 5] since Jan 1."
results in..
It's been 0 years, 1 months, 18 days since Jan 1.
"It's been [countdown "1/1/2010 04:00" 4] since Jan 1."
results in..
It's been 1 months, 18 days since Jan 1.
"It's been [countdown "1/1/2010 04:00" 3] since Jan 1."
results in..
It's been 6 weeks, 6 days since Jan 1.
"It's been [countdown "1/1/2010 04:00" 2] since Jan 1."
results in..
It's been 48 days, 8 hours, 50 minutes since Jan 1.
"It's been [countdown "1/1/2010 04:00" 1] since Jan 1."
results in..
It's been 48 days since Jan 1.
I know this is a pretty esoteric feature, but hey, if someone besides me finds it useful, all the better.
