present simple + since/until

Hello, i was browsing one of my grammar books and bumped into such sentence in which i need to choose either unti or since and i have no clue one should be wrong. Both options are used with specified time moment:

I always stay on duty since/until 6 o'clock.
  

Top answer

Use until here. If talking about a past situation, you could say I had been on duty since 6:00 when the fire started.

  • Use until here.
  • If talking about a past situation, you could say I had been on duty since 6:00 when the fire started.
