hourly cron task overlapping on 2 days-CodePudding

I have to write some cron expressions from a firebase schedule function. As Google's servers aren't in the same timezone as me I will have to convert my existing expressions. (from UTC 2 to UTC-5). Here is an example of one of my expressions: 0 9-17 * * 1-5 - from monday to friday at minute 0 from 9:00 to 17:00

How can I convert this so it will run at this time in UTC 2 when the server is in UTC-5

CodePudding user response：

Because UTC 2 to UTC-5 is 7 hours backwards you should take the time 7 hours backwards:

0 2-10 * * 1-5

When we look at the Firebase Schedule Function documentation found documented here:

https://firebase.google.com/docs/functions/schedule-functions

we find a section called Write a scheduled function. In there we find that when we code:

functions.pubsub.schedule("<CRON String">)

we can add a timeZone setting. For example:

functions.pubsub.schedule("<CRON String">).timeZone('America/New_York')

What this means to us is that we can set a specific time zone against which our CRON intervals will be evaluated. According to the documentation, the default time zone is utc.
