Trying to trigger maintenance via API

Trying to trigger maintenance via API

I have a set of Linux servers that run in AEDT timezone, but my Site24*7 account is in UTC timezone. These servers reboot for maintenance once a week via a cron job, just before running the cronjob I would want to schedule a maintenance by making an API call, but timezone is causing an issue. So if the server sends an API call at just before the cronjob, site 24*7 will take it as UTC time without converting. Is there a work around that you would suggest?
