go-cron jobs not running in railway

Hello, so I'm using the go-cron(https://github.com/go-co-op/gocron) library for managing my cron jobs on my Go web server.

func CharactersIdWeeklyCron() {
    // Cron job for adding character ids every Wednesday at 4am PST
    cron := gocron.NewScheduler(time.FixedZone("America/Los_Angeles", (-8 * 60 * 60)))
    cron.Cron("0 4 * * 3").Do(func() {
        dfo.FindCharacterStats()
    })
    cron.StartAsync()
}

func CharactersStatsDailyCron() {
    // Cron job for adding character stats every day at 3am PST
    cron := gocron.NewScheduler(time.FixedZone("America/Los_Angeles", (-8 * 60 * 60)))
    cron.Cron("*/15 * * * *").Do(func() {
        dfo.UpdateCharacterStats()
    })
    cron.StartAsync()
}
// Setup CRON jobs
if os.Getenv("CRON_ENABLE") == "true" {
    l.Info().Msg("Setup CRON jobs")
    cron.CharactersIdWeeklyCron()
    cron.CharactersStatsDailyCron()
}

func CharactersIdWeeklyCron() {
    // Cron job for adding character ids every Wednesday at 4am PST
    cron := gocron.NewScheduler(time.FixedZone("America/Los_Angeles", (-8 * 60 * 60)))
    cron.Cron("0 4 * * 3").Do(func() {
        dfo.FindCharacterStats()
    })
    cron.StartAsync()
}

func CharactersStatsDailyCron() {
    // Cron job for adding character stats every day at 3am PST
    cron := gocron.NewScheduler(time.FixedZone("America/Los_Angeles", (-8 * 60 * 60)))
    cron.Cron("*/15 * * * *").Do(func() {
        dfo.UpdateCharacterStats()
    })
    cron.StartAsync()
}
// Setup CRON jobs
if os.Getenv("CRON_ENABLE") == "true" {
    l.Info().Msg("Setup CRON jobs")
    cron.CharactersIdWeeklyCron()
    cron.CharactersStatsDailyCron()
}

It runs fine on my local machine, but doesn't seem to run any jobs on railway deployment. It does seem to setup the cron jobs though as can be seen by logs in the screenshot. Would you guys happen to know what could be the reason?

Solution:

I always use UTC on the scheduler because it makes the most sense for server stuff, can you try to initialise each scheduler with UTC?

gocron.NewScheduler(time.UTC)

.atran25•10mo ago

Sure, let me try that out right now Okay yup that fixed it. Thanks for the speedy help!

Brody•10mo ago

no problem! did you want to hear my possible solution that would allow you to use time zones?

.atran25•10mo ago

sure if you have a possible solution I'd love to hear it

Brody•10mo ago

import _ "time/tzdata" this will embed time zone data into the build I assume whatever container railway is running your app in is missing the timezone data and the underscore is very necessary

.atran25•10mo ago

ahh interesting, alright let me try that out importing the time/tzdata did indeed fix the issue fully

Brody•10mo ago

awesome
