# Updating the system time on the NextSeq 1000/2000
If the time on the NextSeq 1000/2000 instrument computer is inaccurate for the time zone in which the the instrument is located, proceed with the following steps to change the time.
1. Close NextSeq Control 1000/2000 Software.
2. Navigate to the top right side of the instrument and open **Account Settings** from the drop-down menu (see Figure 1).
3. Select **Details** > **Date & Time** on the left-hand side, edit the **Date & Time** of the instrument, and ensure the **Automatic Date \&Time** option is ON (see Figure 3).
1. **Note**: If a window for "Authentication Required" opens, enter the root user password in the "Administrator" password field (see Figure 1). If recovery of root password is needed, see [How to change passwords and unlock accounts on the NextSeq 1000/2000](/instrumentation/nextseq-1000-2000/instrumentation-nextseq-1000-2000-troubleshooting-list/000003297.md).
