This selection from the main Platform Administration view lets you change the date and time in the Niagara platform, as well as specify its time zone (Figure 55). The Save button becomes available after you change one or more fields in the dialog, or when you click Use Local.
Upon , any change is processed by that host’s operating system.
The three dialog fields are as follows:
-
Date
Click in a day-month-year position to select, then click up/down controls, or click and type in numerals directly, or click the calendar icon for a popup dialog to select the date from a calendar.
-
Time
Always displays in 24-hour format. Click in a hour or minute position to select, then click up/down controls, or click and type in numerals directly.
-
Time Zone
Provides a drop-down selection list of all available time zones in NiagaraAX. Each time zone provides a text description, and in parenthesis the “hour offset” from UTC (and if daylight savings time is used) the “offset plus daylight savings.” For example:
America/New_York (-5,-4).For more time zone details, see the appendix Time Zones and NiagaraAX.
Although rare, in some cases a platform’s OS may not support a particular time zone. This relates only to a few time zones
with daylight savings switch-over. For example, America/Santiago (-4,-3)is not supported in Windows-based hosts because the start and end daylight savings dates are exact dates, versus a week number and weekday (e.g. 2nd Sunday).Upon clicking for a time zone not fully supported by the host’s OS, a popup dialog (Figure 56) explains that the platform’s OS time zone was set to UTC (+0) during the update.
Typically, if your Workbench PC’s current date/time setting are accurate, you click the “Use Local” to synchronize the remote host’s date, time, and time zone with your Workbench PC. Upon , the remote host will have the identical settings.
To keep time synchronized across multiple Niagara platforms, configure the NtpPlatformService in the station running on each platform, as appropriate.
