Correct way to write time
How would you write the time using the 24-hour clock casually?

The W3 standard uses:
hh:mm:ss
For simple timestamp, with no seconds, try:
1h54m
or:
01h54m
Both are readily parsed by a computer due to the h and m and indicating the end of the numeric.
ISO8601 (https://en.wikipedia.org/wiki/ISO_8601) has a section on periods, so things like "P1D" represents one day, or "P3Y6M4DT12H30M5S" represents a duration of "three years, six months, four days, twelve hours, thirty minutes, and five seconds".
I had a co-worker correct me on an error today and I was just curious about what is actually correct.
I had said “ this happened in the last 1:30 of the shift” by which I meant (last hour and a half of the shift).
I understand you could confuse the 1:30 for 1 min 30 seconds but in the context it wouldn’t have been that.
Was my way incorrect?
"I'll be busy from 2pm til' 4pm," is something I texted someone and it got me wondering that if I say, "I'll be busy from 1400 til' 1600," would that sound/look strange to countries that use the 24-hour clock regularly?
Also considering that, "Busy at 2," or "Busy at 2pm," are just abbreviations of "Busy at 2:00 pm," would there be an abbreviated version with the 24-hour clock? ie. "I'll be busy from 14 to 16."
