Time Options.

There are two sources of time on ClockIOT:

1. NTP - Network time protocol
2. DS3231 Real time clock

ClockIOT comes with a DS3231 real time clock can maintain time to about a minute per year without internet. If internet is available, the current time and timezone will be deterimined using NTP and timezone lookup from IP address. You can always override the timezone the internet provides, but then you will have to keep track of daylight savings time yourself.
