 In other words:  Wattmon "Linux Timestamps" are based upon local Wattmon time and are not adjusted by the timezone setting in Control Panel > Time Settings (Time and Date Settings) > UTC Offset.  (These settings are stored in ''/config/time.ini''.) In other words:  Wattmon "Linux Timestamps" are based upon local Wattmon time and are not adjusted by the timezone setting in Control Panel > Time Settings (Time and Date Settings) > UTC Offset.  (These settings are stored in ''/config/time.ini''.)

 +This differs from the traditional PHP implementation in that the month variable is 0-11 rather than 1-12.  This was due to an early implementation error which we are unable to modify now since too many devices use the code.
