According to Elk's M1 firmware release notes, version 5.2.4 dated 6/14/10 is the last UL version, "currently used in new controls
However Elk has released two subsequent firmware updates: 5.2.6 (2/14/11) and 5.2.8 (7/18/11), both of which have not been evaluated by UL as of the document publication date 7/18/11.
Under version 5.2.8. Elk claims to have fixed the DST problem:
"2. Found and fixed a new problem found in the Daylight Savings Time auto-adjust. This problem manifested itself even when using the M1XEP to access a time server.
Perhaps everyone who is or is not experiencing this problem can report which firmware he's running.
I'm running 5.2.4 and have:
Globals (Misc): Observe daylight savings time CHECKED
Specify: DST Starts [SECOND] [SUNDAY] in [MARCH]
DST Ends [FIRST] [SUNDAY] in [NOVEMBER]
M1XEP checks into a NIST time server daily. (The time server is located in my time zone, not that that should matter...)
Yet my system is currently behind by one hour (no change from standard time).
However I don't recall having a problem last fall going from DST to standard. (I've owned the M1G for less than 1 year.)
A hard reboot of either M1G and M1XEP seems to have no effect on the matter.
