Can anyone help me with this shell script to extract the logs within the specified timestamp. I don’t know what’s wrong with it. this is the script. when i tried to execute it, it says something like there is a error while parsing the date

#!/bin/bash

# Function to convert timestamp to seconds since epoch
convert_to_seconds() {
    local timestamp=$1
    date -d "$timestamp" +%s
}

# Check if correct number of arguments are passed
if [ "$#" -ne 3 ]; then
    echo "Usage: $0 <log_file_name> <start_timestamp> <end_timestamp>"
    echo "Timestamps should be in the format '[HH:MM:SS:SSS][DD-MM-YYYY]'"
    exit 1
fi

log_file=$1
start_timestamp=$2
end_timestamp=$3

# Convert start and end timestamps to seconds since epoch
start_seconds=$(convert_to_seconds "$start_timestamp")
end_seconds=$(convert_to_seconds "$end_timestamp")

# Check if log file exists
if [ ! -f "$log_file" ]; then
    echo "File not found: $log_file"
    exit 1
fi

# Read the log file line by line
while IFS= read -r line; do
    # Extract the timestamp from the log line
    if [[ $line =~ ([[0-9]{2}:[0-9]{2}:[0-9]{2}:[0-9]{3})][([0-9]{2}-[0-9]{2}-[0-9]{4})] ]]; then
        log_time="[${BASH_REMATCH[1]}][${BASH_REMATCH[2]}]"
        log_seconds=$(convert_to_seconds "$log_time")

        # Check if log time is within the specified range
        if [ "$log_seconds" -ge "$start_seconds" ] && [ "$log_seconds" -le "$end_seconds" ]; then
            echo "$line"
        fi
    fi
done < "$log_file"
