So if I put:
$if(df(hhmm)>=700 & df(hhmm)<1200, tf(12h00m00s,hh:mm:ss))$
It will start a countdown from 7 o’clock to 12 o’clock, and the countdown will look like this 05:00:00
And when it reach less than one hour left the countdown gonna be look like this 00:59:59.
The hour gonna be 00, so how do I remove it and make it display 59:59?
Same when it reach less than a minute, how do I make it only display the second?
And my second question is is there a way to make the hour as a minute? For example 02:30:00, how to make it to 150:00 (150 as the minute)
