if your handle client call triggers the wdt you won't notice.
I would print ms value before and after the call.

- Sun Jul 12, 2015 4:49 pm #23083 Suddenly, at 23.30 both my ESP8266 units had already begun to work normally
First:
on http://192.168.1.103/ shows:
hello from esp8266!
and in serial:

Code: Select allwork time [s]= 1226.49
work time [s]= 1226.59
work time [s]= 1226.69
work time [s]= 1226.80
work time [s]= 1226.90
work time [s]= 1226.99
work time [s]= 1227.09
work time [s]= 1227.19
work time [s]= 1227.30
work time [s]= 1227.40
work time [s]= 1227.50
work time [s]= 1227.60
work time [s]= 1227.70
work time [s]= 1227.80
work time [s]= 1227.90
work time [s]= 1228.00
work time [s]= 1228.10


an so on

Second module as termometer with DS18S20
on http://192.168.1.102/ shows:
ESP8266 12750 T=21.30 Time:1280s

After resetting the routers working time is again about 32 seconds
What is going on?

- Sun Jul 12, 2015 6:50 pm #23096 Do you have a link to the millis() function documentation for the function of the Arduino libraries implemented to top of the ESP8266? Here is what is going through my mind.

Your code seems to be writing out the millis() value divided by 1000 to turn it into seconds. Perfect ... get that ... however ... what are "expecting" the millis() output to be? My belief is that the value is a timer that keeps incrementing since boot time. Which means (to me) that it should always be increasing and if one wants to find delta times, one must record the initial value and then subtract that from the current value to find the difference.

Again, I might be totally off base on this having never tried to use (yet) the Arduino IDE/libraries (I code using the raw Espressif SDK and Eclipse).
