Date Format

Grep Badger's UI is built with Angular, so the custom date format uses Angular date formatting. The default value is M/d/yy, h:mm a.

This means the value you enter follows Angular's DatePipe format rules, which are based on Unicode date field patterns.

This is not a .NET DateTime format string reference. Some patterns look similar, but not all .NET tokens work the same way here.

Default format

The default timestamp format is:

HH:mm:ss

Example output:

14:07:32

Common examples

Pattern reference

The table below covers the most useful Angular date format tokens.

Predefined format names

Angular also supports a few built-in format names.

Literal text

Use single quotes to include plain text in the result.

Example:

• Format: 'Time:' HH:mm:ss
• Output: Time: 14:07:32

Another example:

• Format: MMM d, yyyy 'at' HH:mm
• Output: Apr 19, 2026 at 14:07

Tips

• If you want a simple log timestamp, use HH:mm:ss
• If you want milliseconds, add .SSS
• If you want AM/PM, use a
• If you want month names, use MMM or MMMM
• If a format does not behave as expected, make sure you are using Angular date tokens rather than .NET date tokens
