Timestamp
A Timestamp is a way of representing a date and time. The way this date and time is formatted can vary per project, per data source and per region in the world. Therefore, the Tygron Platform provides a means to configure and manage the way dates and times are interpreted for user supplied data.
The Timestamp format used in your project can be changed in in the Project Detail panel. This format will be used to interpret timestamps present in time-values CSV data, used for example by an Inlet Q's dynamic range in the Water Overlay Wizard.
Timestamp format
This format does require a certain symbology. In short we will describe it here. More details can be found at java's DateTimeFormatter patterns.
Symbols
| Symbol | Meaning | Examples |
|---|---|---|
| y | year | 2004; 04 |
| M | month of year | 7; 07; Jul; July; J |
| d | day of month | 10; 31; 4; |
| H | hour of day (0-23) | 0; 4; 13; 23 |
| m | minute of hour | 0, 31, 47, 60 |
| s | second of minute | 55,12, 6 |
Example formats
Example of Timestamp Formats are:
- yyyy-MM-dd
- MM-dd-hh-mm
- dd/MM/yy hh:mm:ss
- yyyy/MM/dd hh:mm:ss
- MM dd yyyy hh
Here the letters indicate the way the numbers are automatically interpreted by the Date parser used in the Tygron Platform. It is important that when you start importing CSV data with timestamps, you should first check what Timestamp formats are in the file and adjust the project's timestamp format to that format.
When you don't configure it correctly, you might receive errors of unrecognized timestamp formats, or worse, import the dates wrongly without any notice.

Important Notes
- minutes are with a small m and Months are with a capital M!
- seconds are with a small s. A large S is a fraction of second (milliseconds)!
- day of month is with a small d. A large D is a day of year!
