This call will alter the /etc/localtime symlink. In Windows time zone settings, the best selection would be Harare which is the closest to Malawi although it’s in a different country. However it keeps resetting back to standard UTC, I'm guessing via a NTP time server. In a typical year there are several countries around the world that make time zone changes. Every time anything happens to a file, at least one element of its status changes, and its ctime is set to the current system time. You’re right, I assumed that timestamps must always be produced by the OS, and that they should always reflect a date which is logical considering when NTFS has been in use. Changing Linux to use local time is easier and more reliable than changing Windows to use UTC, so dual-boot Linux. Set Time, Date Timezone in Linux from Command Line or Gnome | Use ntp Written by Guillermo Garron Date: 2012-04-19 15:55:00 00:00. Coordinated means that several institutions contribute their estimate of the current time, and UTC is built by combining these estimates. 0 (when the date/time functions were rewritten), every call to a date/time function will generate a E_NOTICE if the timezone isn't valid, and/or a E_WARNING message if using the system settings or the TZ environment variable. Available time zones can be listed with list-timezones. DST rules are magic (determined by local law) and can change from year to year. The time is displayed in the UTC format at OS and Database Level. Your Oscar.
