    【Question】
    When was the highest amount of donated? How much was the amount? when refers donation_timestamp; the highest amount refers to max(donation_total)

    【Evidence】
    when refers donation_timestamp; the highest amount refers to max(donation_total)

    Please read and understand the database schema carefully, and generate an executable SQL based on the user's question and evidence. 

SQL: SELECT donation_timestamp, donation_total FROM donations WHERE donation_total = ( SELECT donation_total FROM donations ORDER BY donation_total DESC LIMIT 1 )
