What UTC+12:45 means
A clock set to UTC+12:45 shows UTC plus 12 hours 45 minutes. When it is 12:00 noon UTC, it is 12:45 am next day here. Compared with India (UTC+5:30) it is 7 hours 15 minutes ahead.
Converting to and from UTC+12:45
To turn UTC into this time, add 12 hours 45 minutes. To go back to UTC, subtract the same amount. Three examples: 6:00 am UTC is 6:45 pm here; 3:00 pm UTC is 3:45 am here on the next day; 9:00 am here is 8:15 pm UTC on the previous day. The calendar date changes whenever the sum passes midnight.
Where UTC+12:45 sits on the map
The Earth turns 15 degrees of longitude every hour. The line where the sun-time matches UTC+12:45 exactly is 191.2° east. This offset is not a whole number of hours. Places choose a half or quarter hour when a whole hour would leave their clocks too far from their own sun-time.
Who is on UTC+12:45, and when
No place with a town of 15,000 people or more keeps UTC+12:45 through the whole year. Nobody moves on to or off this offset during the year, so the list below is the same in every season.
