What time formats does UpTime Screen Saver support?

UpTime Screen Saver offers two time formats:

• Short format - Displays a compact time string (e.g., "5d 3h 12m").
• Long format - Spells out the full duration (e.g., "5 days, 3 hours, 12 minutes").

Both formats support optional millisecond precision for exact tracking. Zero values are automatically hidden for cleaner output (e.g., "1 week, 1 hour, 15 minutes" instead of "1 week, 0 days, 1 hour, 15 minutes").
