HP ProCurve Switch 5400zl timezone and daylight saving configuration in Sydney

Only two lines

time timezone 600
time daylight-time-rule user-defined begin-date 10/01 end-date 04/01

HP ProCurve Switch 5400zl has a pre-defined daylight saving configuration “southern-hemisphere”. However, based on HP documentation, it does not apply to Sydney.

Southern Hemisphere:
* Begin DST at 2am the first Sunday on or after October 25th.
* End DST at 2am the first Sunday on or after March 1st.

So we need to setup user-defined rules. Be aware that 10/01 does not mean 1st October, but first Sunday in October. Refer to HP documentation for detail.

It will look like this in ‘menu’ mode after configuration.
