Ok - don't laugh

My coding skills are pitiful so I asked my resident Ai to write a bash
script to call a webcam script (I did write this one) only between
sunrise and sunset. it produced this and it works! My question is - how
can I amend the script so it starts 30 minutes BEFORE sunrise and stops
30 Minutes after?

#!/bin/bash

# Set your latitude and longitude
LATITUDE="mine"
LONGITUDE="mine"

# Fetch sunrise and sunset times in UTC
SUN_TIMES=$(curl -s "https://api.sunrise-sunset.org/json?lat=$LATITUDE&lng=$LONGITUDE&formatted=0") SUNRISE=$(echo $SUN_TIMES | jq -r '.results.sunrise')
SUNSET=$(echo $SUN_TIMES | jq -r '.results.sunset')

# Convert sunrise and sunset times to seconds since epoch
SUNRISE_EPOCH=$(date -d "$SUNRISE" +%s)
SUNSET_EPOCH=$(date -d "$SUNSET" +%s)
CURRENT_EPOCH=$(date +%s)

# Check if the current time is between sunrise and sunset
if [ $CURRENT_EPOCH -ge $SUNRISE_EPOCH ] && [ $CURRENT_EPOCH -le
$SUNSET_EPOCH ]; then
echo "It's between sunrise and sunset. Running the other script..."
# Call the other script
./webcam.sh # Replace with the path to your script
else
echo "It's not between sunrise and sunset."

Since you already have the date/times in seconds since the epoch, just add/subtract 30 minutes worth of seconds for AFTER and BEFORE!

Why not just ask the AI goonbot to do that?

How about

SUNRISE_EPOCH=$(($(date -d "$SUNRISE" +%s) - 1800))
SUNSET_EPOCH=$(($(date -d "$SUNSET" +%s) + 1800))
