Cron job timezone problems: how to run cron in a specific time zone (and survive DST)

Cron job timing issues often arise because cron relies on the system time zone, leading to errors during DST changes. Users can verify settings via timedatectl to manage these traps. Meanwhile, serverless platforms like Vercel, Cloudflare Workers, and Netlify offer alternative scheduling methods since they lack traditional crontabs. Vercel allows users to define schedules in vercel.json, which triggers specific API routes, though configuration and failure handling vary across these different serverless providers.
