Clock and Time zone configuration
RouterOS uses data from the tz database, Most of the time zones from this database are included, and have the same names. Because local time on the router is used mostly for timestamping and time-dependant configuration, and not for historical date calculations, time zone information about past years is not included. Currently only information starting from 2005 is included.
Following settings are available in the /system clock console path, and in the "Time" tab of the "System > Clock" WinBox window:
- time (HH:MM:SS, where HH - hour 00..24, MM - minutes 00..59, SS - seconds 00..59)
- date (mmm/DD/YYYY, where mmm - month, one of jan, feb, mar, apr, may, jun, jul, aug, sep, oct, nov, dec, DD - date, 00..31, YYYY - year, 1970..2037) : date and time show current local time on the router. These values can be adjusted using the set command. Local time cannot, however, be exported, and is not stored with the rest of the configuration.
- time-zone-name (manual, or name of time zone; default value: manual) : Name of time zone. Like most of the text values in RouterOS, this value is case sensitive. Special value manual applies manually configured GMT offset, which by default is 00:00 with no daylight saving time.
- time-zone-autodetect (yes or no; default: yes) : This is new feature, starting from 6.27. If enabled, time zone will be set automaticaly.
Note: Time-zone-autodetect by default is enabled on new RouterOS installation and after configuration reset. The time zone is detected depending on routers public IP address and our Cloud servers database. Since RouterOS v6.43 your device will use cloud2.mikrotik.com to communicate with the MikroTik's Cloud server. Older versions will use cloud.mikrotik.com to communicate with the MikroTik's Cloud server.
Startup date and time is jan/02/1970 00:00:00 [+|-]gmt-offset. If router has a battery (for example RB230), then BIOS stored time is used as a startup time.
Active time zone information
- dst-active (yes or no>; read-only property) : This property has value yes while daylight saving time of the current time zone is active.
- gmt-offset ([+|-]HH:MM - offset in hours and minutes; read-only property) : This is the current value of GMT offset used by the system, after applying base time zone offset and active daylight saving time offset.
Manual time zone configuration
These settings are available in /system clock manual console path, and in the "Manual Time Zone" tab of the "System > Clock" WinBox window. These settings have effect only when time-zone-name=manual. It is only possible to manually configure single daylight saving time period.
- time-zone, dst-delta ([+|-]HH:MM - time offset in hours and minutes, leading plus sign is optional; default value: +00:00) : While DST is not active use GMT offset time-zone. While DST is active use GMT offset time-zone + dst-delta.
- dst-start, dst-end (mmm/DD/YYYY HH:MM:SS - date and time, either date or time can be ommited in the set command; default value: jan/01/1970 00:00:00) : Local time when DST starts and ends.
