Specifying timezone causes no trigger using croner <= 7.x

[jefbarn]

This doesn't do anything:

  Cron('* * * * * *', { timezone: 'America/Anchorage' }, () => {
    console.log('test')
  })

This works:

  Cron('* * * * * *', () => {
    console.log('test')
  })

Interersting, can confirm this happens with multiple timezones resolving to AKDT.

@jefbarn Please check if upgrading to croner@7.0.6-dev.0 resolves this issue.

[jefbarn]

Verified croner@7.0.6-dev.0 is working with timezone: 'America/Anchorage'
Thanks!

Released in stable channel through 8.0.0

Thanks for the fix @Hexagon . However I tried the 7.0.6-dev.0 branch with Node.js 16 and it throws the following error:

RangeError: Value shortOffset out of range for Date.prototype.toLocaleString options property timeZoneName

I'm guessing the syntax in 7.0.6-dev.0 is only supported for Node.js >= 18. We're unable to move to Node.js 18 at the moment due to hardware vendor limitation. Is there any chance you can make this bugfix work with Node.js 16? Thx again.

@victorird Oh, thanks for reporting this! Released a potential hot fix in croner@7.0.6-dev.1 (channel croner@legacy-node-support), where i added the following code as a quick workaround for AKDT and AKST not being supported by Date.parse():

	// Convert non-supported timezones
	// - Hotfix for AKST and AKDT 7.0-branch of Croner, fixed for real in 8.0
	tz = tz.replace("AKST","-0900").replace("AKDT","-0800");

Hacky, but i hope it should do for those who cannot go to 8.x. Please let me know if this works for you, and i'll release 7.0.6 stable.

Thanks for the quick hot fix. I tested it and it's working flawlessly!

Nice! Added support for AST and released croner@7.0.6-dev.2, will let this version linger for a while before releasing the stable version.

Resolved in the 7.x branch through 7.0.7
