Pokud náhodou používáte GPX2000 od výrobce Grandstream, tak zde je návod jak na telefonu nastavit přechod při změně času.
The "Automatic Daylight Saving Time Rule" shall have the following syntax:
start-time;end-time;saving
Both start-time and end-time have the same syntax:
month,day,weekday,hour,minutemonth: 1,2,3,..,12 (for Jan, Feb, .., Dec)day: [+|-]1,2,3,..,31weekday: 1, 2, 3, .., 7 (for Mon, Tue, .., Sun), or 0 which means the daylight saving rule is not based on week days but based on the day of the month.hour: hour (0-23),minute: minute (0-59)
If "weekday" is 0, it means the date to start or end daylight saving is at exactly the given date. In that case, the "day" value must not be negative.
If "weekday" is not zero and "day" is positive, then the daylight saving starts on the first "day"th iteration of the weekday (1st Sunday, 3rd Tuesday etc).
If "weekday" is not zero and "day" is negative, then the daylight saving starts on the last "day"th iteration of the weekday (last Sunday, 3rd last Tuesday etc).
The ‘savings time’ is in the unit of minutes. The saving time may also be preceded by a negative (-) sign if subtraction is desired instead of addition.
The default value for "Automatic Daylight Saving Time Rule" shall be set to "03,02,7,02,00;11,1,7,02,00;60" which is the rule for US.
