Dates and Times
Every LogTag® product contains a real time clock, which it uses to determine the recording start time, when to take a reading and when to stop recording.
Often, the loggers are used for transit monitoring applications, where goods are transported between different countries, and frequently different time zones.
Time zone information is included in the loggers' memory, allowing you to relate shipments from different time zones to each other.
During configuration with a PC, the clock of each logger is set to the computer's time, and the local time zone of that computer is also stored in the logger's memory. When the logger is downloaded by the recipient, LogTag® Analyzer is able to use the time zone information from the logger and the information from the PC used for downloading to display the data in a variety of different time zones.
| Time zone | What is displayed |
|---|---|
|
Local PC Time Zone |
All times are displayed in the time zone of the computer used for viewing the data. This is the most commonly used option, as it displays the dates and times on screen in your local time zone. Note, that this is not the same as the download time zone, if you were sent a file from a logger downloaded in a different time zone. |
|
Download Time Zone |
All reading times are displayed relative in the time zone of the computer used for downloading the data. |
|
All reading times are displayed in the time zone of the computer used for configuring the LogTag®. You would use this option if you wanted to view the data in the same way the sender of the logger would see it. |
|
|
UTC/GMT Time Zone |
All times are displayed in Greenwich Mean Time (Universal Time Coordinated). This is the best option when comparing different loggers from different senders in different time zones. |
The currently used time zone is shown on the status bar:
The default time zone used when first opening a file is set in the options settings. If you quickly want to switch to another time zone, without affecting all other charts, you can click on Select Display Time Zone and choose the desired the time zone from the list.
