/var/log/messages: Core VMkernel logs, including device discovery, storage and networking device and driver events, virtual machine startup, and a merged copy of the hostd and vpxa management service logs.

/var/log/vmware/hostd.log: Host management service logs, including virtual machine and host Tasks and Events, communication with the vSphere Client and vCenter Server vpxa agent, and SDK connections.

/var/log/sysboot.log: Early VMkernel startup, module loading, and host initialization.

you could also use uptime, which will report

17:33:15 up 1 day,  5:13, load average: 0.00, 0.00, 0.00

othwerwise it's probably best to use Syslog, to send the alerts to a syslog server, ass events are overritten, but if you check the /var/log/sysboot.log you will see the dates and times of server start.

Messages, hostd, will not retaing the logs in ESXi, also tough to find the multiple reboot events from these logs ( Even from vMA)

uptime will only give the last reboot details

var/log/sysboot.log doesnt have any time stamp details, only file modified date is the reference

Please let me know any command to find the reboot details & command for last reboot (other than uptime)

uptime will only give the last reboot details

your question:- Command to dispaly the last reboot time

I've got timestamps in our /var/log/sysboot.log!

Again, Setup a syslog server, to retain this data.

If you want to display ALL the reboot times, you will need to setup a Syslog server.

ESXi only logs to memory, and that you need to set logging to a syslog server to preserve logs between reboots.

If you want exact information you need to set logging to a syslog server

ESXi only logs to memory, and that you need to set logging to a syslog server to preserve logs between reboots.
