Grandstream GXP21XX daylight saving time.

[YonNomNom]

Hello all.
Daylight savings time is about to end in Melbourne Australia and now all our Grandstream handsets are showing the incorrect time. The PBX is correct.

I posted a job with Grandstream and they fixed the calculation used on the handsets but it has not been updated in 3CX's template for version 15.5.0 and it's been over 6 months now Link to initial post

3CX template still shows the incorrect calucation for
GMT+10:00 (Sydney, Melbourne, Canberra) Current:

EST-10EDT-11,M10.5.0/02:00:00,M3.5.0/03:00:00

That says that on the 5th Sunday of October (there is no 5th Sunday) daylight savings starts and ends on the 5th Sunday of March.

It should read

EST-10EDT-11,M10.1.0/02:00:00,M4.1.0/03:00:00

It should say that on the 1st Sunday of October daylight savings starts and ends on the first Sunday of April

Hello @YonNomNom

The change has been made for the new templates that are available in V16 so if you upgrade you should be ok.


Unfortunately these templates have not be tested with V15.5 and could cause other issues if used.

Does this fix includes the one for GMT-5?
