Usage tips
Compound word
The word is made up of 'die Zeit' (time) and 'die Umstellung' (changeover). 'Umstellung' comes from the separable verb 'umstellen' (to change over / to reset) and here means changing the clock time.
EXAMPLE
Die Umstellung der Uhren erfolgt in der Nacht von Samstag auf Sonntag.
The changing of the clocks takes place during the night from Saturday to Sunday.
Typical collocations
Common formulations are 'die Zeitumstellung findet statt' (the time change takes place), 'sich an die Zeitumstellung gewöhnen' (to get used to the time change), or 'Probleme mit der Zeitumstellung haben' (to have problems with the time change).
EXAMPLE
Manche Menschen brauchen eine Woche, um sich an die Zeitumstellung zu gewöhnen.
Some people need a week to get used to the time change.
Use with 'auf'
To indicate the direction of the change, the preposition 'auf' is used. People speak of the 'Zeitumstellung auf Sommerzeit' (time change to daylight saving time) or the 'Zeitumstellung auf Winterzeit' (time change to standard time).
EXAMPLE
Im Frühjahr freuen sich viele auf die Zeitumstellung auf Sommerzeit.
In spring, many people look forward to the time change to daylight saving time.

Zeitumstellung vs Sommerzeit
daylight saving time / summertime
'die Sommerzeit' and 'die Zeitumstellung' are both connected to the clock. 'Sommerzeit' names the period during which the clock is set forward by one hour. 'Zeitumstellung' names the process in which the clock is changed, that is, the switch between daylight saving time and standard time. Learners may confuse the words because they are often used in the same conversation. If you mean the period of time, say 'Sommerzeit'. If you mean the moment or process of changing the clocks, say 'Zeitumstellung'.

Nach der Zeitumstellung brauchen viele Menschen ein paar Tage, bis sie wieder gut schlafen.
After the time change, many people need a few days before they can sleep well again.
