Mismatch in timezones causes synchronize to detect change when there is no change to the file

I transferred 2 files successfully using synchronize. I see them on the server as:
-rw-r--r--. 1 ec2-user ec2-user 12838665 Mar 19 07:10 proddata/KTCL-master-data-20230318.xlsx
-rw-r--r--. 1 ec2-user ec2-user 13033878 Mar 20 16:47 proddata/KTCL-master-data-20230321.xlsx
When I run synchronize again:
The WinSCP logs says:
. 2023-05-10 20:23:46.368 Local file 'D:\proddata\KTCL-master-data-20230318.xlsx' [2023-03-19T07:10:12.625Z] [12838665] is modified comparing to remote file 'proddata/KTCL-master-data-20230318.xlsx' [2023-03-19T01:40:12.000Z] [12838665]
. 2023-05-10 20:23:46.369 Local file 'D:\proddata\KTCL-master-data-20230321.xlsx' [2023-03-20T16:47:40.021Z] [13033878] is modified comparing to remote file 'proddata/KTCL-master-data-20230321.xlsx' [2023-03-20T11:17:40.000Z] [13033878]
And then it transfers the files again.

The WinSCP is running on a Win Laptop in IST timezone.
The server uses UTC.
This is on WinSCP 5.21.7.

Please post session log file both for the session that transfers the files originally and the session that re-transfers the files again.

File transfer logs

Here are the logs. I am using SCP protocol.
Description: Second transfer. The same files get transferred again as WinSCP thinks the local files are modified. The local timezone is 4.5 hours ahead of UTC.
Description: First transfer

In the remote directory listing, WinSCP sees the timestamp as
2023-03-19 07:10:12

When doing the comparison, it shifts the timestamp of the remote file to 2023-03-19T01:40:12.000Z.

Not sure why this behaviour.
