What is the cron expression in Quartz Scheduler to run a program at 12 am every midnight GMT.
I have never used quartz before so I am still learning.
Is the expression 0 0 12 * * ? or is that for 12 pm (noon). Could anyone tell me?

Show activity on this post. ->cron('0 */12 * * *'); This cron will run the scheduler at every 12 hours.
0 * * * * -this means the cron will run always when the minutes are 0 (so hourly) 0 1 * * * - this means the cron will run always at 1 o'clock. * 1 * * * - this means the cron will run each minute when the hour is 1.
Cron job every night at midnight is a commonly used cron schedule. We created Cronitor because cron itself can't alert you if your jobs fail or never start. Cronitor is easy to integrate and provides you with instant alerts when things go wrong. Learn more about cron job monitoring.
1 Seconds 2 Minutes 3 Hours 4 Day-of-Month 5 Month 6 Day-of-Week 7 Year (optional field)
So in your case:
0 0 0 * * ?
This will fire at midnight, if you want to fire at noon:
0 0 12 * * ?
Or both:
0 0 0,12 * * ?
