Hello everybody,

I am running in a strange issue with time formulas in Performance Equations.

In order to get shift time (at 6 AM, 14 PM, 22 PM) and avoid problems with DST change dates, I am getting the beginning of the shift in 2 ways:

- 't+1d-18h', which should be equal today at 6 AM; instead it returns tomorrow at 12AM
- 't-18h+1d', returns yesterday at 6 AM

Am I doing something wrong?

If I use 't+6h' I would have problems with DST change days

Fund out the following:

multiple offset can lead to problems.

Anyhow I solved it like this to get 6 AM of today:

't+1d'-(18*3600)
