時 combines 日 (sun, day) with 寺, which historically contributed the sound and the idea of a measured unit. The combination expresses time as measured by the sun's movement.
The sun 日 beside a temple 寺 suggests measuring time by the sun's position over the temple. When the sun reaches a certain spot, an hour has passed.
For ジ, imagine a giant clock on the temple wall that makes a buzzing 'ji' sound every hour: ji -> ジ, marking the time.
