Astute readers will have noticed that the code I put here recently for switching themes by time of day had an off-by-one bug. I was attempting to turn the day theme on at 7am and the night theme on at 7pm. The code was
$hour = (int) date ("G"); if ($hour < 7 || $hour > 19) $theme = "summer_night"; else $theme = "summer_pool"; print " ";
This worked well, except that the night theme was switching on at 8pm, not 7pm. However, as it is still light at 9pm in summer, I thought it appropriate to leave the code running as is, and change my notes on the league website to say that it changes at 8pm. Much easier.
If I really wanted to switch at 7am and 7pm, the if statement should be this:
if ($hour < 7 || $hour >= 19)
