Cron's timing - using GMT?

[Sergey Imennov]

Hi.

        I was under the impression that cron used 'local'
        time for timing events, however, I was surprised,
        when, I started seeing the 'updatedb' at
        something like 6am.

        Is using GMT for cron normal for UNIX, or is this
        something new?

Thanks,
Nikita
