Adjusting the System Time

The V2403-LX has two time settings. One is the system time, and the other is provided by an RTC (Real Time

Clock) built into the V2403- LX’s hardware.

Setting the Time Manually

Use the date command to query the current system time or set a new system time. Use hwclock to query the

current RTC time or set a new RTC time.

Use the following command to set the system time.

moxa@Moxa:~# date MMDDhhmmYYYY

MM: Month

DD: Date

hhmm: Hour and Minute

YYYY: Year

Use the following command to write the current system time to the RTC.

root@Moxa:~# hwclock

root@Moxa:/home/moxa# date ; hwclock

NTP Client

The V2403-LX has a built-in NTP (Network Time Protocol) client that is used to initialize a time request to a

remote NTP server. Use ntpdate to update the system time.

#ntpdate time.stdtime.gov.tw

#hwclock –w
