Time and Clocks

The actual time at home was 7:05. Mirror reflection shows 4:55 (mirrored horizontally). Joey rides for 20 minutes and arrives at camp at 7:25, which is exactly 2.5 hours after 4:55. Working backwards from the given constraints confirms 7:25 as the arrival time.

Maxima watches uses the tagline "Because times are changing" to position itself as a modern, evolving watch brand for changing times. The other options are watch brands, but this specific slogan belongs to Maxima.

In Tamil scientific terminology, 'Kaalam' is the precise term for the concept of time. 'Mani' colloquially refers to clock or hour, 'Neram' is the general word for time in everyday usage, and 'Vinadi' specifically means minute. Scientific Tamil distinguishes between the concept and its measurements.

Let current time be T hours from midnight. If 1 hour later: (T+1) hours until midnight. If 2 hours later: (T+2) hours until midnight. Condition: (T+2) = 0.5 × (T+1). Solving: T+2 = T/2 + 0.5, so T/2 = -1.5, giving T = -1.5, meaning 1.5 hours before midnight, which is 10:30 PM. Wait, that gives negative. Let me recalculate: Let hours UNTIL midnight = h. Then h - 1 = 0.5(h). So h - 1 = h/2, giving h/2 = 1, so h = 2. If 2 hours until midnight, current time is 10 PM. But let me verify: At 10 PM, 1 hour later = 11 PM (1 hour until midnight), 2 hours later = midnight (0 hours until midnight). But 0 ≠ 0.5×1. Let me try 9 PM: 1 hour later = 10 PM (2 hours until midnight), 2 hours later = 11 PM (1 hour until midnight). And 1 = 0.5×2. Yes! The answer is 9 PM. The claimed answer B is correct.

The time() function returns seconds since the Unix epoch: January 1, 1970, 00:00:00 UTC. This is the standard reference point used by Unix-like systems. Dates before this are represented as negative values.

The Munich air disaster occurred on 6 February 1958 when the plane carrying the Manchester United team crashed at 3:04 PM. Old Trafford's clock is permanently stopped at this exact time to honor the 23 people who died, including 8 players. The other times (4:05 pm, 18:11 pm which is an invalid format, and 11:01 am) do not match the historical record.

'15 minutes to 10' means 15 minutes before 10 o'clock, which is 9:45. In time notation, 'to' indicates 'before' the stated hour.

Indian Standard Time (IST) is 5 hours 30 minutes ahead of Greenwich Mean Time (GMT). India is at 82.5°E longitude, which is 5.5 hours ahead of the Prime Meridian (0°). IST does not observe daylight saving time.

This is a wordplay riddle that relies on how the phrases sound when spoken. The correct answer 1:45 is a pun on the wording of the riddle rather than a mathematical calculation.

Indian stock markets (NSE and BSE) close trading at 4:00 PM IST on weekdays. The pre-open session runs from 9:00-9:15 AM, followed by normal trading hours from 9:15 AM to 3:30 PM, with a closing session from 3:30-4:00 PM.

True - a jiffy is indeed used as a unit of time in various contexts. In electronics and computing, a jiffy is commonly defined as 1/60 or 1/100 of a second (the duration of one alternating current power cycle). However, definitions vary: in physics it's the time light takes to travel one centimeter, and in different computing contexts it can be 1/10, 1/50, or 1/60 second depending on the system.

The CMOS (Complementary Metal-Oxide-Semiconductor) battery maintains the BIOS settings and system clock configuration when the computer is powered off. When this battery becomes weak or dies, the system cannot retain date/time settings, causing them to reset every time the computer restarts. This is a common hardware issue in older computers. Motherboard issues or OS corruption would typically cause different symptoms.

The hands of a clock coincide 22 times in a 24-hour period. They coincide once every hour, but because the minute hand must 'catch up' to the moving hour hand, the overlap happens roughly every 65 minutes, skipping two overlaps daily.
