Daylight Savings Configuration for EST

Hey everyone,

 

I've got my NTP config in place but I probably need to do something to correct for DST as currently I am an hour off. I have set my timezone to EST by using:

 

clock timezone EST minus 4:00:00

 

Now I need to setup DST. As far as I can tell, I have to use this command:

 

clock summer-time <TMZ> repeating <starttime> <startdate> <endtime> <enddate> <timeoffset>

 

Where TMZ is the 3 letter/4 letter/ timezone indicator. Start time is in hh:mm:ss format and indicates the time in which DST begins. Start date is in mm/dd/yy format that marks the date in which it starts. Endtime is in hh:mm:ss and indicates the time in which DST ends. Enddate is in hh:mm:ss and indicates the date in which DST ends. Timeoffset is in hh:mm:ss and indicates the skew for DST.

 

My question is DST occurs on different dates each year. Does this command some how understand the floating time offset dates?

I am also in the EST timezone. These are the commands I use on my switches, and they work for me:

 

time timezone -300
time daylight-time-rule Continental-US-and-Canada
