My syslog time and the kernel's time seem to be in different timezones and cron is not picking up.

Hey all,
I have a droplet in the Bangalore region and I'm facing a problem where my crons are not being picked up if I specify a time.
This is what I've debugged so far:

sudo tail -f /var/log/syslog

Apr 27 00:45:01 by2rides-app-2 cron[1021]: (*system*by2rides-auto-create) RELOAD (/etc/cron.d/by2rides-auto-create)

I created this file /etc/cron.d/by2rides-auto-create itself at exactly Apr 27 10:20 - so clearly the syslog is in a different timezone.
Additionally, I also checked this.

cat /etc/timezone 
Asia/Calcutta

And my cron.d was very specific:

21 10 * * 1-5 root curl --request GET http://localhost:8080/xyz

The cron is not being piked up. However, if I change it by removing concept of time altogether and keep it at a interval, it gets picked up. So clearly we have timezone issues !

*/5 * * * 1-5 root curl --request GET http://localhost:8080/xyz

Anyone else faced this issue ?

I am not sure how the syslog and kernel could have two different reported times. With your original cron configuration does the task run but just at the wrong time?

UPDATE

I just found the solutions for my situation - restarting rsyslog. After setting up chrony for desired NTP and clock management, I neglected to restart the logging daemon. Once this was done, all now seems right and proper.

ORIGINAL POST

I have this exact same issue. To verify this is only on DO, I built 2 other CentOS VMs on my ESX server and other cloud infrastructure. None experience this issue - only my DO droplet has this discrepancy.

Anyone have some suggestions or solution to fix this? I suspect there is something in the DO infrastructure that is forcing some syslog messages to be reported using UTC rather than the local time of the server.
