10.7. Using the Real Time Clock Function
The real time clock in the module keeps track of the number of seconds since the module was powered on
and the actual time when synchronized with the sNTP time server. By default the module keeps track of up
time but does not synchronize with the time server since this requires being associated with a network that
can access the sNTP server.
The Real Time clock reads the time is seconds since 1970. This corresponds to the Unix time.
In version 2.23, it is now possible to set the RTC value in seconds using the set time rtc <value> command
from console.
The default sNTP server is at
ADDR=129.6.15.28:123
ZONE=7
(GMT -7)
Use the show time command to see the current time and uptime
<2.23> show t
Time=08:43:10
UpTime=10 s
To set the time, use the time command.
<2. 23> show t
Time NOT SET
UpTime=8 s
<2. 23> time
<2. 23> show t
Time=08:51:31
UpTime=15 s
NOTE: the WiFly module must by successfully associated with a network for the module to contact the
sNTP server.
Alternatively, the module can be configured to get the time whenever it powers up by setting the time
enable to 1. Any value greater than 1 pulls time continuously every <value> minutes.
To configure the WiFly module to get time upon power up
<2. 23> set time enable 1
