Hi Fabian, there is only one special value:
defaultTimeFrame which is used on Dashboard when you set your default timeframe
Other non-special values are regulary prefixed by type of GTF:
p_, c_, l_, e_
Examples:
- Custom: c_123456789_0 with two timestmaps where 0 stands for current time
- Last: l_6_HOURS, l_365_DAYS
- Problem: prefixed with p_ have problem id attached
- Expressions are new type that comes from input above GTS: e_-2h, e_today
Expressions are default format and do not need prefix, so we can type in url gtf=-2h or gtf=yesterday.
Read more about them in recent blog post.
Reference: Customize Dynatrace analysis timeframes as never before with the new global timeframe selector
