8 Configuring Regional Parameters and Supplementary Services Localizing Your IP Phone For example, the default DST rule is start=4/1/7;end=10/-1/7;save=1. The start-time and end-time values specify the start and end dates and times of daylight saving time. Each value is in this format: month/day/ weekday[/HH:mm:ss] The month value equals any value in the range 1-12 (January-December). The day value equals any + or - value in the range 1-31. If day is 1, it means the weekday on or before the end of the month (in other words the last occurrence of weekday in that month). The weekday value equals any value in the range 1-7 (Monday-Sunday). It can also equal 0. If the weekday value is 0, this means that the date to start or end daylight saving is exactly the date given. In that case, the day value must not be negative. If the weekday value is not 0 and the day value is positive, then daylight saving starts or ends on the weekday value on or after the date given. If the weekday value is not 0 and the day value is negative, then daylight saving starts or ends on the weekday value on or before the date given. Optional time values: HH represents hours (0-23), mm represents minutes (0-59). and ss represents seconds (0-59). Optional values inside brackets [ ] are assumed to be 0 if not specified. Midnight is represented by 0:0:0 of the given date. The save-time value is the number of hours, minutes, and/or seconds to add to the current time during DST. The save-time value can be preceded by a plus (+) or minus (-) sign to indicate addition or subtraction.
